We want to determine if there are differences between three age groups on their mean cholesterol scores. We compare a group of participants who are young adults to a group of middle aged adults and finally a group of older adults to see if there are differences in cholesterol scores by age group.
What is the independent and the dependent variables and the level of data for each variable?
Homework Answers
Independent variable: the variable which is supposed to be affecting the other variable.
Here, the independent variable is the age group of an individual.
Dependent variable: the variable which is affected by the other variable.
Here, the dependent variable is the cholesterol scores of the individual.

We
want to determine the strength of the relationship between the
independent variable "age" and the dependent variable "intelligence
quotient". In our sample, the mean of the variable "age" is equal
to 14, and its variance is equal to 46,4. The mean of the variable
"intelligence quotient" is equal to 102, and its variance is equal
to 0. The list of corresponding data for the two variables is
pictured below.

Part I: Between-Groups Design In the between-groups design, researchers were interested in whether cholesterol levels would differ depending on diet. Twenty participants were randomly assigned to one of two different groups. Group A was assigned a diet rich in fruits and vegetables and with no trans fats. Group B participants were asked to follow their normal diets, which contained varying levels of trans fats depending on the individual. After one month, blood samples were drawn and the following levels of...

Suppose you perform an ANOVA on 18 subjects divided evenly into three groups according to age. Reading speed is measured and averaged for cach of the three groups. The reading speed for the Young Group is 10; for the Middle Group, 12; and for the Older Group, 13. Your F is 9.15. Use obf a=05 a. What are your degrees of freedom? b. What is the appropriate P? crit c. What should you conclude?

Question 7 2 pts A researcher is interested in whether there are significant differences between 5-year olds, 10-year olds, and 15-year olds in working memory scores. In planning his hypothesis tests, the researcher identified age as the independent variable and working memory as his dependent variable. Can the researcher use an independent-samples t test to test his hypothesis? Why or why not? Yes, because there is one nominal independent variable and one scale dependent variable No, because the independent variable...

We want to examine the efficacy of the current flu vaccine at preventing the flu. Once flu season is over we ask 500 people if they got the vaccine and if they contracted the flu. We then break them into groups (those who got the vaccine and those who did not) and compare them based upon whether or not they contracted the flu. A. Identify the Independent (IDV) and dependent variable (DV) in this problem and identify the level of...

Assume total cholesterol levels (TChol) are normally distributed with mean μ = 215 mg/dl and standard deviation σ = 30 mg/dl for the adult American population. That is, TChol ~ N(215, 302). Total cholesterol values of 240 mg/dl or greater are considered high; and levels in the range of 200 to 240 are called borderline high. a. What proportion of this population do we expect to find with high cholesterol? What proportion do we expect to find with borderline high...

We want to compare the mean weight of an all meat diet to the mean weight of an all spam diet. We believe the mean weights are not the same for these two diets. We randomly assign subjects to one of two groups, an all meat diet group and an all spam diet group. The all meat groups consist of 50 people who have a mean weight of 180 and a standard deviation of 20. The spam group also has...
