The control group in the following experiment:
Mr. Stevens wanted to see if his new technique for underwater flips improves the times for the swim team. He teaches the technique to the part of the team that swims backstroke only.
What is the part of the swim team that does not swim backstroke?

The treatment group in the following experiment:
Mr. Stevens wanted to see if his new technique for underwater flips improves the times for the swim team. He teaches the technique to the part of the team that swims backstroke only.
What is the backstroke swimmers?

Why is the following biased?
“You want to determine which superhero movie franchise – Marvel or DC – is preferred. People were interviewed leaving Avengers Endgame.”
What is cluster?
Only surveyed those coming from a Marvel Movie

The flaw in the following experiment:
Mr. Stevens wanted to see if his new technique for underwater flips improves the times for the swim team. He teaches the technique to the part of the team that swims backstroke only.
What is cluster?
Mr. Stevens did not randomize the groups leading to data that doesn't show the whole picture

using the following curve find the percent that is between 86 and 130?
What is 83.85%?

The problem with the following experiment:
A researcher wants to test the effectiveness of meditation on blood pressure. The following describes the experimental design:
The researcher is given 100 volunteers who have high blood pressure. 50 of the volunteers meditate. After one month, the patients are evaluated.
What is sample size? The size of the sample is too small.
Will also accept
What is cluster?
They only looked at high blood pressure not normal and low
