I am having trouble with independent and dependent variables. Here is a problem from my home work.
Krusty Krabs Breath Mints:
mr. K created a secret ingredient for a breath mint that he thinks will cure bad breath people get from eating his crabby patties. he asked a 100 customers with a history of bad breath to try his new mint. He had 50 customers (group A) eat a breath mint after finishing a crabby patty. The other 50 (group B) also received a mint but it was just a regular mint that did not have the secret ingredient. Both groupd were told they were getting the breath mint that would cure their bad breath. Two hours after eating crabby patties, 30 customers in group A and 10 customers in Group B reported having better breath than normal.
1. Which people are the control Group? I think it is A.
2. What is the independent variable?
I think it is eating a crabby patty
3. What is the dependent variable?
I think it is having a breath mint.
4. What should Mr. Krab's comclusion be?
Have a breath mint after every patty
6. Why do you think 10 people in group B reported fresher breath?
That the breath mint really worked
Am I on the right track?
Thanks
1. Which people are the control Group? I think it is A.
2. What is the independent variable?
I think it is eating a crabby patty
I would think the taking/not taking the breath mint is the indep variable
3. What is the dependent variable?
I think it is having a breath mint.
Isnt the dependent variable bad/good breath?
4. What should Mr. Krab's comclusion be?
Have a breath mint after every patty
6. Why do you think 10 people in group B reported fresher breath?
That the breath mint really worked or it works for some people, or the measurement of good breath is subjective and nonprecise
