Mr. Pochettino created a secret ingredient for a breath mint that he thinks will “cure” the bad breath people get from eating fish tacos at the Taco Tent. He asked 100 customers with a history of bad breath to try his new breath mint. He had fifty customers (Group A) eat a breath mint after they finished eating a fish taco. The other fifty (Group B) also received a breath mint after they finished the taco, however, it was just a regular breath mint and did not have the secret ingredient. Both groups were told that they were getting the breath mint that would cure their bad breath. Two hours after eating the fish tacos, thirty customers in Group A and ten customers in Group B reported having better breath than they normally had after eating fish tacos. What did Mr. Pochettino measure in his experiment? Identify the independent variable, dependent variable, and what Mr. Pochettino's conclusion should be.

Explanation:

The group that is recieving the 'intervention' is the experimental group. & The group of people that are not receiving the intervention,they are only for comparison purpose with the experimental group is the control group.

The outcome of the experiment is the dependent variable.

The rest of the variables are independent variables.

1)The people that are not receiving the new breath mint ,are the control group. Group B is the control group.

2)All the customer (both Group A & B ) had bad breath at the start of study i.e., before intervention.

So, Bad breath is an independent variable.

Secondly, all the person are eating krabby patties.

So, ingestion of krabby patties is also an independent variable.

3)The outcome of the study is dependent variable.

So bad breath get cured/or not is the dependent variable.

4)Group A is receiving the new breath mint.So Group A is the experimental group.

The independent variable is are all of the variables left after the dependent variable is recognized.  The dependent variable is the result of the expierement.  Independent variables: Stinky breath and ingestion of the tacos.  Dependent variables: The outcome of the expierement.  The outcome is basically rather or not the stinky breath was cured or not.  Mr. Pochettino's conclusion should be that the secret ingredient, does indeed, definately have a positive effect on curing stinky breath.

Explanation:

The group of people that are collecting the 'intervention' is known as the experimental group of people.  The group that is not collecting the 'intervention', well, they are simply just for comparison purposes along side the experimental group.  The experimental group of people  is also known as the group that is in charge.  The dependent variable is whatever the outcome of the experiment is and the independent variables are all of the variables that are left.  Group B is the group that is in charge.  They are the people that will not receive the new breath mint.  Both, group A and group B, had stinky breaths at the start of this study.  This means before intervention.  First, with that being said, bad breath is then known as an independent variable.  Second, all of the people are eating fish tacos.  That then makes ingestion of the tacos an independent variable as well.  With all of this now recognized, the outcome of the study is known as the dependent variable.  Basically, the dependent variable is if the stinky breath is cured or not cured.  Finally, group A is receiving the new breath mint making them now the experimental group.

what are the choices?
