Answer #1

The table is:

Categorical Variable Parameter Coding
EVER DIAGNOSED WITH A STROKE Frequency (1) (2)
Yes 133 1 0
No 1860 0 1
Don't Know 7 0 0

From the above table, we can see that the variable we are looking at is whether the person have been ever diagnosed with a stroke.

From a sample of 2000 respondents, we see that there are 133 respondents who have ever been diagnosed with a stroke. 1860 respondents have never been diagnosed with a stroke. 7 respondents however didn't know about it.
From the sample, we can say that the probability of a person being diagnosed with a stroke randomly chosen is 133/2000 = 0.0665

The probability of a person not being diagnosed with a stroke randomly chosen is 1860/2000 = 0.93

The assignment is: Next, in SPSS, run frequency distributions for each of the categorical variables and descriptive statistics for each of the continuous variables. Consider also creating a graph or chart in SPSS to describe these distributions. For variables that have very small frequencies in at least one category (e.g., less than 7 people in a category), think about combining that category with another if it makes conceptual sense (i.e., there are very few Native Americans, does it make sense...
