If im trying to determine correlation between two variables, BMI & ethnicity what kind of stastical test should i run? Race is a independent categorical , and nominal. BMI is dependent is quantitive and continuous
Homework Answers
Here basically we want to know whether there is an association between a categorical and a numerical variable.
To test this we will have to perform an ANOVA test where we can consider Race as Treatment and BMI as a study variable.

Researchers want to know if there is a correlation between BMI and systolic blood pressure in males over 50. A random sample of 9 males is selected and their data is recorded below. a) Calculate the Pearson Correlation Coefficient for these two variables and b) test whether the correlation is significantly different from 0. Run the test at a 5% level of significance. Give each of the following for part b to receive full credit: 1) the appropriate null and...

8) Suppose the correlation coefficient between two variables is -0.897. Does the dependent variable increase or decrease as the independent variable increases? O a. The dependent variable will decrease as the independent variable increases. O b. The dependent variable will remain constant as the independent variable increases. The dependent variable will remain constant as the independent variable increases. The dependent variable will increase as the independent variable increases.

I'm confused on how to approach this question, what statistical tests should I run to receive the required information? The data related to the health knowledge assessment scores in continuous and the variables it should be tested against are categorical. Test the association between the student’s health knowledge assessment score and the demographic variables (Gender, Race, and Family Income) and the behavior variables (Body Image, Sexual Activity, and Risk Behavior). Quantify the magnitude and significance of the association between the...

What is your initial understanding of a correlation between two variables? What does correlation mean to you, as your first thought? Describe how to present data to make it more understandable to yourself and others. Explain various types of charts or graphs and appropriate levels of data (nominal, ordinal, scale) for each. How does this fit in with the comment "it's not one size fits all"?
