Give an example of a case that has both a categorical and quantitative variable someone might be interested in examining.

An example of a case that has both quantitative and categorical variables could be a study of the average salary between a male and female. The salary would be the quantitative variable and the gender of the person would be the categorical variable. Another example could be a study of GPA’s from different large public universities such as IU or Purdue. The GPA’s are the quantitative variables and the universities are the categorical variables.

Describe an instance where a graph/chart/histogram/etc. or a median/mean given that was misleading and did not reveal the whole situation.

I am sure we all see misleading graphs or charts on a daily basis. Many times, the misleading factor on charts I see have to do with the numerical values. People will make the Y axis begin at say 50 instead of 0. Then the numbers go up in increments of 5. So, if it starts at 50 and one point on the chart is at 60 and another is at 70, it can mislead the visual interpretation of a chart making one bar seem twice as large than another when in reality it is only a few numbers higher. There needs to be some sort of baseline and that should usually be 0.

A two-variable model involving one quantitative explanatory variable and one categorical (binary) explanatory variable (and no interaction), results in two regression lines that are: A. Always parallel. B. Could be parallel but, depending on the data, may not. C. Never parallel. D. Always horizontal. The two methods of including a binary categorical variable in a regression model are to use indicator coding or effect coding. For indicator coding in the two-variable model (with no interaction): A. The binary variable is coded (-1,1) and the coefficient...

Age - Quantitative vs Categorical 99 unread replies.99 replies. It's important to consider how a variable is being used when determining if it is quantitative or categorical. For example, a researcher can study blood pressure by recording the systolic followed by the diastolic pressure and then calculate statistics like the mean and median diastolic reading in millimeters of mercury (mm Hg). In this case, the researchers would be studying blood pressure as a quantitative variable. On the other hand, a...
