Why would you choose to use an ANOVA instead of a t test?
The t-test is a method that determines whether two populations are statistically different from each other, whereas ANOVA determines whether three or more populations are statistically different from each other.
In which situation would it be appropriate to use one-way Anova?
The One-Way ANOVA is commonly used to test the following: Statistical differences among the means of two or more groups. Statistical differences among the means of two or more interventions. Statistical differences among the means of two or more change scores.
What is the difference between paired t test and one-way Anova?
One-way repeated measures ANOVA RMA is also referred to as within-subjects ANOVA or ANOVA for paired samples. (In paired samples t test, compared the means between two dependent groups, whereas in RMA, compared the means between three or more dependent groups).
When to use a one-way ANOVA instead of a paired t test?

When to use a one-way ANOVA in data collection?
When to use a one-way ANOVA. Use a one-way ANOVA when you have collected data about one categorical independent variable and one quantitative dependent variable. The independent variable should have at least three levels (i.e. at least three different groups or categories).
When to use student’s t test and ANCOVA?
Student’s t test (t test), analysis of variance (ANOVA), and analysis of covariance (ANCOVA) are statistical methods used in the testing of hypothesis for comparison of means between the groups. The Student’s t test is used to compare the means between two groups, whereas ANOVA is used to compare the means among three or more groups.
When to use a paired sample t test?
Paired samples t-test. This is used when we wish to compare the difference between the means of two groups and where each observation in one group can be paired with one observation in the other group. For example, suppose 20 students in a class take a test, then study a certain guide, then retake the test.
