Can ANOVA be used for pre and post test?
A within-subjects ANOVA is also called a repeated measures ANOVA.
This type of test is frequently used when using a pretest and posttest design, but is not limited to only two time periods.
The repeated measures ANOVA can be used when examining for differences over two or more time periods..
How do you Analyse before and after data?
The usual statistical method for comparing the pre- to the post-analysis is called the two-sample t-test.
For each outcome of interest, you can perform a t-test to decide whether there is a statistically significant difference between the new version of the site versus the old..

List of statistical tests and when to use them
Paired T-test
It tests the difference between two variables from the same population (pre-and post-test scores).
For example, measuring the performance score of the trainee before and after the completion of the training program..
List of statistical tests and when to use them
Two main statistical methods are used in data analysis: descriptive statistics, which summarizes data using indexes such as mean and median and another is inferential statistics, which draw conclusions from data using statistical tests such as student's t-test..
Types of statistical tests in research
Paired samples t-test– a statistical test of the difference between a set of paired samples, such as pre-and post-test scores.
This is sometimes called the dependent samples t-test.
For every observed change in one student's pre-test score, there is an expected change in that student's post-test score..
What is before and after study statistical analysis?
The final method involves collecting data before and after an intervention but without a control group.
Researchers know this method as the Before-After design.
This design is the simplest, but it's also the least powerful as it cannot control for extraneous variables, and it cannot determine causality..
What is the statistical test for before and after treatment?
Paired ttest – An extremely powerful test for detecting differences (it is, in fact, the most “sensitive” of all our five tests).
It is usually used for “Before vs.
After” type experiments, where the same individuals are measured before and after the application of some sort of treatment..
