This channel keeps a record of just how I've been wasting my time recently. That is all. I don't post videos.
Stata Basics - Executing and interpreting bivariate hypothesis tests
In this video, I illustrate 3 simple hypothesis tests for checking the relationship between two variables: the crosstab (1:10), the difference of means test (8:00), and one-way ANOVA (13:10)

Stata Basics - Collapsing variables with if statements
Просмотров 3,7 тыс.4 года назад
In this short video, I cover how to take a variable on a larger scale and collapse it to substantially the same variable on a smaller scale through the use multiple, simultaneous "if" conditions.
Stata Basics - Constructing an Index
Просмотров 17 тыс.4 года назад
This video covers how to construct a simple additive index using multiple variables, as well as to accomplish the necessary setup tasks including modifying the values and scale of the variable. This video assumes that you are familiar with the "generate" command. This video was prepared for social science undergraduates taking a course in research methods. It assumes that viewers are comfortabl...
Stata Basics - Tour of the Interface
Просмотров 504 года назад
This video provides a tour of the basic features of the Stata interface including the results pane, command prompt, variables pane, and data editor. This video was prepared for social science undergraduates taking a course in research methods. It assumes that viewers are comfortable with basic data concepts but lack experience and/or comfort with Stata itself.
Stata Basics - Creating New Variables with Generate and Replace
Просмотров 6874 года назад
This video demonstrates how to use the commands "generate" and "replace" to manipulate variables using Stata. Specifically, I cover how to take an existing variable with many values and breaking it down into a variable with few values. There's a lot more you can do with these commands, but using them to create simple dichotomous and ordinal variables is one of the most common use cases. This vi...
Hello Mr, thank you for the insightful explanation. I want to ask about bivariate chi-square in Stata. In this video have a result of Bartlett's test: chi2(4) = 11.4252, what is the interpretation of this Mr? Thanks in advanced
This video has just helped with my assignment straight to the point thank u
Guys how to make an index when the data is unscaled? I have a 3 variables that are ratios
Thank you, you helped me alot with this
very helpful
Hi, thank you for your video. I have a question about something which has to be easy to understand - but I don't get it: the original scale of both variables is 1-3. But why is the scale in the new generated index from 0-4 (012345) ?!
Because the index is the sum of the two variables (conmedic + consi2) and shows different combinations of values that these two variables can take. For example, if a respondent reports a great deal of confidence in medicine and science, the index takes the value of 4. If a respondent reports only some confidence in medicine but a great deal of confidence in science the index takes the value of 3 this time.
Thank you for your video, you can use the stata command codebook [var] to see what variables are originally coded numerical wise. I wish you showed multiple ways to construct indices but for now making sure they are all on the same scale and adding them up will have to do the job.
you chose the most comfortable dataset for u and created index which means nothing. Thank you!
thankyouuuuuuuuuu you've really saved me
Very helpful, thank you!
