I really want to write something to summarize my work，Unfortunately, I was too busy with work and never got around to writing。I’ve been having some time recently and wanted to discuss with you about creating 188bet Live Casino models。

1. Establishment of 188bet Live Casino model and collection of questionnaire data

Persona: (Persona is the abbreviation of 188bet Live Casino model) is a fictitious 188bet Live Casino used to represent a 188bet Live Casino group。A persona can be more representative than any real individual。

First，188bet Live Casino model is a division of users，It is to transform the concept of a class into a role。Here is a simple example: there are many characters in the movie，But are there any characters in life that are exactly the same as those in movies?Obviously very few，Unless you meet the best。The characters in the movie are representative characters that combine the commonalities of a large number of characters，Represents a type of person or a group。

188bet Live Casino are mixed in large numbers，We need to separate 188bet Live Casino according to roles to determine the combination of preferences and scenarios for different roles，This is the main purpose of establishing the persona system。

The following is a detailed description of the steps to establish a Persona system。

Many experts talk about establishing a Persona system，A rookie like me doesn’t dare to do anything in my job，I personally prefer Dr.Lene Nielsen’s 10-Step Persona Method。

Finding the 188bet Live Casino Discovery 188bet Live Casino

Building a hypothesis Establishing a hypothesis

Verifications survey Finding patterns Discover common patterns

Constructing personas constructing fictional characters

Defining situations defining scene goals

Validation and buy-in Review and buy

Dissemination of knowledge dissemination of knowledge

Creating scenarios creating scenarios

On-going development Continuous development

Follow Dr.Lene Nielsen’s method can establish a complete 188bet Live Casino model system (although I am not very good at using some of them)，However, this method is still a bit mysterious for most products。When I first came into contact with this thing, I watched it all afternoon and still didn’t quite understand how to use it。So it can only be based on this advanced stuff，I have summarized a set of feasible Persona model construction methods and plan to briefly talk about them below，I am a rookie，Please give us your opinions！

Step 1: Identify the 188bet Live Casino and make assumptions

First，It is necessary to clarify the 188bet Live Casino groups，This should be clear before most applications are developed。Developing a crude product without even knowing the 188bet Live Casino base。Secondly，Make 188bet Live Casino role assumptions。Everyone will ask at this time，I originally wanted to determine the 188bet Live Casino role model，Isn’t this putting the cart before the horse?？？I want to explain something，Before 188bet Live Casino role analysis，We need to have a direction for dividing users。For example, for a game，We want to divide the 188bet Live Casino model，In fact, there are many ways to divide it。Users can be divided into，Junior player、Intermediate player；can also be divided into，Strategic toys、Visual Player、Equipment player。Any 188bet Live Casino group has multiple classification methods，First we need to determine how we classify users。After determining the classification method，Let’s study each category one by one。

The following is a simple example of an Internet medical product I work on，To illustrate this point。This is just a simple example，The real 188bet Live Casino model hypothesis classification is much more complicated than the example。

First, simply define the 188bet Live Casino group: people with non-emergency physical illnesses。

If 188bet Live Casino is an emergency or serious illness, you will usually go directly to the hospital，Does not open mobile applications to consult a doctor or ask for medication instructions。So our applicable group is people who have physical abnormalities that are not urgent。

Make assumptions，For the convenience of examples，We simply divide 188bet Live Casino roles into: careful care types、Extensive type。Careful care type: mainly refers to paying great attention to one's own health，Don’t let go of every problem。Extensive type: Just need to know that something is okay，Not too concerned about his own health。Let’s simply divide 188bet Live Casino roles into these two types，Continue to the second step of analysis。

Step 2: Determine 188bet Live Casino points of interest (extract variables)

For this step，Can be done with a small number of 188bet Live Casino interviews，In fact, it is to find the points that all users pay attention to，We call these 188bet Live Casino concerns variables。

For example, for medical products，After interviews with users，We briefly summarize 188bet Live Casino attention as: the true reliability of doctors、Doctor’s level of responsibility、Can I register with a local doctor、Product Vision、Product interaction。For the convenience of examples，We briefly summarize these 5 features that users are concerned about。Thus we can see，We get 5 variables，The following will design a questionnaire to analyze the differences between these five variables for users with different roles。

Step 3: Design the questionnaire (the most critical step)

The questionnaire is a survey of real 188bet Live Casino groups of our products，So the design of the question must be very targeted，And the results can achieve our expected results。

First，First divide the questionnaire questions into three areas: the screening question area、Variable problem area、Suggestive question area。Someone may want to ask whether these are some magic horses？？？Actually these are very simple。Discrimination issues，is used to identify which role the 188bet Live Casino belongs to；For example, I set 10 questions，Conforms to 1，3，The 188bet Live Casino with 5 questions belongs to role A，Conforms to 2，4，The 188bet Live Casino with 6 questions belongs to role B。

Discriminating 188bet Live Casino:

Take the example just now，We simply set 3 screening 188bet Live Casino:

Z1. How long do 188bet Live Casino usually spend online consulting on your condition?

A.<5min B.5-10min C.10-20min D.20min

Z2. Do 188bet Live Casino need to consult a doctor at any time?

A.Need B.Not required C. 188bet Live Casino depends on the situation

Z3.If there is a small cut on the hand，Not very serious，188bet Live Casino will？

A. Disinfect and bandage immediately B. What to do after cleaning C. Don’t care at all

We define the screening rules as follows:

For the convenience of examples，We simply set the above rules for character identification。Here are a few points，First，Rules are set by people，Can be changed，Only better rules，There are no right or wrong rules；Second，Question 1、Question 2、The relationship between question 3 is "and"，The options in the question are "or" relationship。

There is a question，If none of the 188bet Live Casino’s answers satisfy the above rules，How to assign 188bet Live Casino roles？？？The answer is simple: either really study the rules and change them；Or clean the 188bet Live Casino as data cleaning (indicating that the 188bet Live Casino did not answer the question seriously，Or the 188bet Live Casino belongs to a very small group)。Of course there is still a lot that can be optimized in this place，Refer to data mining information for details。

Variability problem:

Variable questions actually refer to setting questions based on 188bet Live Casino concerns。The focus we just summarized with the example is: the authenticity and reliability of doctors、Doctor’s level of responsibility、Can I register with a local doctor、Product Vision、Product interaction，5 aspects，1-n questions can be set for each aspect。(For simplicity，Only one question listed per variable)

The following is an example of one variable raising multiple 188bet Live Casino:

Product interaction:

What are your requirements for the smoothness of page rotation?

Please give 188bet Live Casino on a scale of 1-100 (1 means don’t care，100 means you care a lot)

How often do 188bet Live Casino operate mobile applications?

Please give 188bet Live Casino on a scale of 1-100 (1 means infrequently，100 represents frequent operation)

Do 188bet Live Casino prefer flat interaction design or deep three-dimensional interaction design？

Please give 188bet Live Casino on a scale of 1-100 (1 means you like flat interaction design，100 means like deep three-dimensional interactive design)

…

Anyway，When designing variable problems，It’s better to get quantifiable numbers，188bet Live Casino will facilitate future multiple regression statistical work。

Suggested question:

Suggestive questions are requests made to us without 188bet Live Casino roles，They may raise some non-global variable issues。For example，For elderly users，It may be suggested that there is a magnifying glass function in the application design，But this function is obviously not suitable for young people。Many suggested questions can be set as open questions，Users without roles can write out their thoughts，If everyone needs it，Then it becomes a new demand，That is, the development direction of product functions。

Following the example we just gave, here are 2 suggested 188bet Live Casino:

J1. As a 188bet Live Casino, what other functions do you want our application to add？

Voice service function

24-hour service hotline

Chinese English Other_______

J2. How would 188bet Live Casino like us to contact 188bet Live Casino?

Telephone

email

Write a letter (haha, here’s a retro way)

Directly to your door

Other_______

At 188bet Live Casino point, our set of questionnaires is completed.

One last thing，At the end of the questionnaire，I want to give a comprehensive evaluation question！！！！

Overall satisfaction:

What is your satisfaction with our application？Please give it on a scale of 1-100 (1 means very dissatisfied)，100 means very satisfied) Okay，Done，188bet Live Casino is a complete set of persona questionnaire。

The picture above describes the process，A villain of each color，After the representative passes the screening issue，Distinguished 188bet Live Casino roles。

Finally, use the above questionnaire to interview 10 188bet Live Casino，The data obtained are as follows:

Description:

P1, P2, P3...P10 represents 10 188bet Live Casino;

Z1, Z2, and Z3 represent 3 screening 188bet Live Casino;

B1、B2、B3…B5 represents 5 variable problems；

J1 and J2 represent 2 suggested 188bet Live Casino

Discrimination question results:

188bet Live Casino are classified according to screening questions as follows:

Careful care type: P1、P2、P4、P5、P10

Extensive type: P6, P7, P9

188bet Live Casino anomaly questionnaire: P3, P8

The generation of abnormal data is usually caused by 2 reasons，The first one is that the screening logic setting is imperfect，For example, our example has few identification problems，Many situations have not been considered clearly，So when designing and screening problems，Try to think through all situations as clearly as possible，To avoid too much invalid data；The second one is that the surveyed 188bet Live Casino did not fill in the form seriously，This is also a very common question，While setting up questions，Minimize tedious problems，Enable the surveyed users to complete all questions more accurately。

Variability question results:

188bet Live Casino survey results are displayed in the form of a numerical table，This is conducive to multiple regression analysis。

Suggestive question results:

Overall satisfaction:

2. 188bet Live Casino processing: Conventional processing of 188bet Live Casino

For the 188bet Live Casino just obtained，Can be processed normally。That is, find the average value or share for corresponding comparative analysis，The results obtained are as follows。

The above survey results are calculated for a sample size of 10，Careful care type accounts for 50%，Extensive type 30%，Abnormal 188bet Live Casino 20%。

Variability problem average:

The average 188bet Live Casino for each role is as follows:

It can be concluded from the above data，Yes, B1-B4 questions，The opinions of the two 188bet Live Casino roles are not much different。But extensive users pay more attention to B5 (product interaction) issues than careful users。

After analyzing the suggested 188bet Live Casino, the following chart can be obtained:

The conclusion can be drawn from this，Careful users have a strong desire to remove email；Extensive 188bet Live Casino tendencies and writing methods。For added service items，Both roles are in demand。

In summary，We just gave a very, very 2b and simple example to illustrate the method of building a 188bet Live Casino model，The sample size of the experiment is also small。This simple example illustrates the basic approach，To truly apply it to your own case，Needs careful study and analysis。

Multiple regression method to analyze 188bet Live Casino model

Good children’s shoes for mathematics，A multiple regression statistical method can be given to analyze the 188bet Live Casino we obtained。The writing here is not detailed，I haven’t heard of hypothesis testing either，Looking for more advice and exchanges from experts。We only use multiple regression methods to analyze the results of variable problems。

Our 188bet Live Casino raises 5 variability issues，So the linear equation to be regressed has 5 variables，The form is as follows:

Y=b0+b1x1+b2x2+b3x3+b4x4+b5x5

Our goal is to deal with b0、b1、b2…b5 calculates the estimate。

Written as a matrix in the form of Y=BX

where Y is the comprehensive satisfaction 188bet Live Casino

Use regress(y in MATLAB,x) can perform multiple regression on B,The results are as follows:

(No hypothesis testing, etc. are performed here，Everyone can improve 188bet Live Casino by themselves)

-0.0868 %b1

0.2210 %b2

0.1407 %b3

0.2041 %b4

-0.0671 %b5

b0 is a constant，No effect on variables，The remaining corresponding variable problems。It can be seen that the B2 issue is the most weighted factor in the overall evaluation of all 188bet Live Casino。
