what are some real world examples when a person might use an independent samples t-test and a dependent samples t-test?
Solutions
Expert Solution
There is very basic difference between when to use independent samples t-test and a dependent samples t-test
If the sample values are obtained from different attributes then it is independent samples t-test
and if same observation is tested twice then it is dependent samples t-test
Example:
Let us suppose you have a diet plan and you want to check if it reduces the weight
You take 10 people and weigh them and then put them on diet.
now, after two weeks you again measure the weight of same peopel and compare if there is a significant difference in their weight
This is a case of dependent samples t-test
Now,
You know in you locality certain people work out regularly
You observed there weight and you also take the observations of people who do not work out at all
and compare if there is a significant difference in their weight
This is a case of independent samples t-test
