## What research method is best suited to examine causes and effects?

A controlled experiment is the only research method that can establish a cause and effect relationship.

## What research method do you employ for determining cause and effect?

Descriptive, or qualitative, methods include the case study, naturalistic observation, surveys, archival research, longitudinal research, and cross-sectional research. Experiments are conducted in order to determine cause-and-effect relationships.

**What are the key steps or considerations when planning a study?**

Basic Steps in the Research Process

- Step 1: Identify and develop your topic. Selecting a topic can be the most challenging part of a research assignment.
- Step 2 : Do a preliminary search for information.
- Step 3: Locate materials.
- Step 4: Evaluate your sources.
- Step 5: Make notes.
- Step 6: Write your paper.
- Step 7: Cite your sources properly.
- Step 8: Proofread.

**What is p value in Z test?**

The first way to find the p-value is to use the z-table. In the z-table, the left column will show values to the tenths place, while the top row will show values to the hundredths place. If we have a z-score of -1.304, we need to round this to the hundredths place, or -1.30.

### Why do we use t-test and Z test?

We perform a One-Sample t-test when we want to compare a sample mean with the population mean. The difference from the Z Test is that we do not have the information on Population Variance here. We use the sample standard deviation instead of population standard deviation in this case.

### What is the difference between t-test and F-test?

t-test is used to test if two sample have the same mean. The assumptions are that they are samples from normal distribution. f-test is used to test if two sample have the same variance.

**What are the 3 types of t tests?**

There are three main types of t-test:

- An Independent Samples t-test compares the means for two groups.
- A Paired sample t-test compares means from the same group at different times (say, one year apart).
- A One sample t-test tests the mean of a single group against a known mean.
