I need this in an HOur please

Identify the types of variables you would need to conduct a Chi-square (last name begins with A-H), one-sample t-test (last name begins with l-P) and paired t-test (last name begins with Q-Z. Be sure to explain the number of dependent and independent variables, and the types of dependent variables necessary for the statistical analysis. Furthermore, provide a health related example (or using a peer-reviewed article that used a chi-square test) to explain your answer

Solution

chi square

we use a chi square test when we need to find if there is a relationship between variables ( if there are independent or not)

or when we have expected value and observed value and we need to know if the problem follow a distribution in specific with contengency tables

expected and observed value

one sample t test

we use t test when we have a sample of a population and we want to know if the mean of population is equal to some value X, or if there is greater than a value in specific or lower that X,

sample mean and sample standard deviation and sample size

paired t test

we use paired t test when we have paired values for examples 2 values for one observation, when we compare 2 groups in the same conditions

sample mean and sample standard deviation and sample size for both population
