Question

finalize three research questions relating to your selected dataset. Make sure the variables used in the final questions you select are of the following format:

1. Continuous response and continuous explanatory variable

2. Categorical response and categorical explanatory variable

3. Continuous response and categorical explanatory variable (note: the categorical variable must be dichotomous for this question)

Study of Interest: The Framington Heart Study

My 10 variables chosen:

CURSMOKE (currently smoking cigarettes): categorical-dichotomous

AGE: continuous- ratio

SEX: categorical-dichotomous

DIABETES: categorical-dichotomous

HEARTRTE (heart rate): continuous-ratio

BPMEDS (anti-hypertension medication): categorical-dichotomous

STROKE: categorical-dichotomous

BMI(body mass index): continuous-ratio

HYPERTEN (hypertension): categorical-dichotomous

CVD (cardiovascular disease): categorical-dichotomous

Explanation / Answer

1. Age , Heart Rate and BMI are the only 3 countinuous variables which you have considered for your study.

Now the response variable is the variable which you want to predict by the help of explainatory variables. Like you can predict Age by looking at the Heart Rate and BMI and so on for any conbinations.

So the possible combinations of response and explainatory variables here are 3

(i)...Age -> Response

Heart Rate and BMI -> explainatory

(ii)... Haert Rate -> Response

Age and BMI -> explainatory

(iii).....BMI -> Response

Heart Rate and Age -> explainatory

2. same as for continuous you have to do the process for categorical variables

there are total 7 varibles where 6 out of 7 will be explainatory and 1 will be response variable

the 7 variables are CURSMOKE ,SEX,DIABETES,BPMEDS ,STROKE,HYPERTEN & CVD

So there are 7 combinations

(i) response = CURSMOKE

explainatory = rest all except CURSMOKE (i.e. SEX,DIABETES,BPMEDS ,STROKE,HYPERTEN & CVD)

and so on for rest 6 cases

3.Categorical response and continuous explainatory varible then we can pick any combinations of continuous variables from  Age , Heart Rate and BMI (And when i say combination it could be any 1 ,any 2 or all 3 could be explainatory variables)

But the response variable should be 1 only from all the categorical variables and since it's given that the categorical variable must be dichotomous and here all are dichotomous we can pick any variable and check the impact of continuous variable's any combination on all the categorical variables 1 by 1)

Hope the above answer has helped you in understanding the proble. Please upvote the ans if it has really helped you. Good Luck!!
