To what extent does socioeconomic status impact the number of new deaths by firearm suicide in males ages 15-34?

Null Hypotheses

There is no correlation between SES and number of new deaths by firearm suicide in males ages 15-34.

Alternative Hypothesis:

There is a correlation between SES and number of new deaths by firearm suicide in males ages 15-34.

Economic status would be the independent variable as changes (in income) may lead to changes in the status of the dependent variable. The cumulative incidence of new deaths by firearm suicide is the dependent variable that will be measured.

I would just look at income. Changes in economic circumstances (income) may have an effect on the cumulative incidence of new deaths by firearm suicide.

-Identify Population 1 and Population 2

-Are the variables continuous, ordinal or nominal?

-What statistical test would you use and why?

-What significance level would you use and why?

Solution

Popultion 1: socioeconomic status

Population 2: number of new deaths by firearm suicide in males ages 15-34

The first variable socioeconomic status is a ordinal variable. It is not continuous. And the variable numner of deaths is a discrete variable.

Here we will conduct the test for popultion correlation coefficient.

The common level of significance is 0.05.
