Step 16: Installation completed.



 

It is best that the collected data should be in an excel sheet. This makes it easier to copy and edit. An already existing dataset will be used as an example.


Please see that the observations of variables 'Sex' and 'did you eat cake in the past 7 days' are denoted as 1 &2 and 0 &1 respectively. For the variable 'sex', we will be considering 1 as male and 2 as female. Whereas, for the variable did you eat cake in the past 7 days', we will be considering 0 as 'no' and 1 as 'yes'. 
 

Step1: Copy the data from the excel sheet.



 

Step 2: Open Stata. Go to the command pane and enter the command 'edit' and click enter

Step 3: A data editor window will appear, where you can copy the data from the excel sheet. Make sure that you copy the data into the first cell in the data editor. You will find a pop-up message asking 'Do you want to treat the first row as variable names or data'. Click 'variable names' and the dataset will be created.

Step 1: Go to the command pane and enter the command 'varmanage'. This command opens the variables manager window.




 

Step 2: You can see the properties displayed on the right side for the selected variable (in this case 'interviewid'). If you want to edit any properties of the variables, you can choose any variable from the left side table and change the properties from the right-hand side table.

Variable properties: 
1. Name: Should not contain any numbers or special characters
2. Label: It is basically how the variable name appears in an output. This can be changed as per your requirement.
3: Type: How the data is being stored.
4. Format: It is auto-generated.
5. Value label: set of responses that are valid for a question(multiple choice). 
6. Notes: for reference purpose

Step 3: For example, earlier we saw that for the variable 'sex', the observations were denoted as 1 and 2, where 1 is male and 2 is female. Now we need to specify it in the variable properties by creating values in the value label.
Select the variable 'sex' from the left-hand side table and click the 'manage' option of the Value label. Then select 'create label'.

Step 4: A 'create label' window will pop-up, where you need to add the label name, i.e., variable name (in this case 'sex'). In the value section type '1' and in the label section type 'Male'. Then click 'add'.



Same way, In the value section type '2' and in the label section type 'Female'. Then click 'add'. Then 'OK'. The set of values for variable 'sex' is added.

Step 5: Now, go to the variable manager window and assign the value label and click 'apply'. The value label will be added to the left-hand side table.






The Variable name is changed to 'cake'. 'Yes' & 'No' values are also added. (1 means Yes and 0 means No)

Step 6: Now, go back to the main STATA window. You will see all the changes made displayed in the Result Pane.

Step 1: Let's find out the frequencies of males and females in the dataset. For this, type the command  'tabulate sex' in the command pane.

Step 2: We can calculate measures of central tendency (mean and median) and measures of variability (Range and Standard deviation). For this, we will be using the variable 'Age'. For this, Use the command 'summarize age'. 

Step 3: We can get more from the summary by giving summarize command and option code 'detail'. Let's see. Type 'summarize age, detail'. This will display, extra details like Skewness and Kurtosis.

Now let's see how to create a graph with the available data. We will be taking the variables 'sex' and 'rice' as examples.

Step 1: Let's create a pie chart for the variable 'sex'. Go to the command pane and type 'graph pie, over(sex)'. (note: in order to produce a pie chart. variable names are added inside the bracket). The command is the same for creating a bar and dot chart. You can replace the word 'pie' with either bar or dot and the same will be produced accordingly.


 

Step 2: Creating Histogram
For creating a histogram, the command is a bit different. Here, we will be using the variable 'age'. Type 'histogram age, normal' in the command pane. (note: the variable name is written after the histogram.)
