Prove if eating oat bran reduces cholesterol in males and females

Goal

Cholesterol =

Population- People with high cholesterol everywhere.

Sample-500 patients who have high cholesterol.

Subjects

Gather 1000 patients with cholesterol equal to or above 240 Mg/Dl

Number patients 0-1000 Using a random number generator, produce

500 unique numbers The 500 numbers selected correspond to the

500 subjects receiving a treatment

Selection of Patients

Blocking will be done by separating genders before random assignment.

Cholesterol has different effects in men and women.

Blocking will allow the tester to compare reductions in cholesterol per gender.

Blinding is not necessary The results are not

opinionated The results are quantitative

numbers that will be collected through medical tests done by authorized doctors.

Blinding

A placebo is not necessary There is no need to change the perception of

the subjects because the results of treatments will not be opinion based.

Giving the patients something else to eat, even though it is not oat bran, may skew the results.

Placebo

The variable that will be measured and compared is the cholesterol level of patients before and after the month of eating or not eating oat bran.

Dividing the patients into gender allows for a useful comparison to see if there is any change in cholesterol level within males or females
