What type of statistics test would I run for 2 different treatments assessed using 5 measurements at 4 different time points?

What kind of statistical test should I use to compare two groups?

A common way to approach that question is by performing a statistical analysis. The two most widely used statistical techniques for comparing two groups, where the measurements of the groups are normally distributed, are the Independent Group t-test and the Paired t-test.

How do I know which statistical test to use?

For a statistical test to be valid, your sample size needs to be large enough to approximate the true distribution of the population being studied. To determine which statistical test to use, you need to know: whether your data meets certain assumptions. the types of variables that you’re dealing with.

Which statistical test would be used for the comparison of more than two proportions?

In order to compare the means of more than two samples coming from different treatment groups that are normally distributed with a common variance, an analysis of variance is often used. In its simplest form, ANOVA provides a statistical test of whether or not the means of several groups are equal.

Should I use ANOVA or t-test?

There is a thin line of demarcation amidst t-test and ANOVA, i.e. when the population means of only two groups is to be compared, the t-test is used, but when means of more than two groups are to be compared, ANOVA is preferred.

What is chi-square test used for?

A chi-square test is a statistical test used to compare observed results with expected results. The purpose of this test is to determine if a difference between observed data and expected data is due to chance, or if it is due to a relationship between the variables you are studying.

What statistical test is used for two independent groups?

Two independent samples t-test

An independent samples t-test is used when you want to compare the means of a normally distributed interval dependent variable for two independent groups.

What are the different types of t tests?

There are three types of t-tests we can perform based on the data at hand: One sample t-test. Independent two-sample t-test. Paired sample t-test.
Paired Sample t-test

  • t = t-statistic.
  • m = mean of the group.
  • µ = theoretical value or population mean.
  • s = standard deviation of the group.
  • n = group size or sample size.

What is a 2 independent sample t-test?

The two-sample t-test (also known as the independent samples t-test) is a method used to test whether the unknown population means of two groups are equal or not.

What are the types of statistical treatment?
