Identify and list categorical and continuous variables.

PH 520 West Coast University Week 4 Categorical and Continuous Variables Statistics Project

Week 4 Database

With this database, you will:

Identify and list categorical and continuous variables.

alculate frequencies and percentages for all of the categorical variables, and means, and standard deviations for the continuous variables.

Run a one-sample z test of proportions for one categorical variable. Here is an example in terms of wording: “Is the proportion of English speaking patients greater than 50%?” Using .05 level of significant test the appropriate hypotheses.

Write the null and alternate hypotheses

What is the proportion of English speaking patients

What is the standard error and z statistics

Find critical z and p value. Is the p value significant? Conclusion?

Run an independent samples t-test to compare two groups of people (specified by a dichotomous variable) on one continuous variable. Using .05 level of significant test the appropriate hypotheses. In order to run this test statistics you have to re-arrange your data.

Write the null and alternate hypotheses.

What is the calculated mean for each group?

What is the confidence interval for each group?

What is the critical t value?

Is the p value significant? Conclusion?
