The Data

GPA dataset details

?gpa

GPA_IQ dataset details

?gpa_iq

What is the relationship between GPA and IQ?

#CREATE a visualization to compare gpa and iq. DESCRIBE what you see

What is the relationship between GPA and Study Hours?

#CREATE a visualization to compare gpa and iq. DESCRIBE what you see

Based on the visualizations above, which variable influences GPA to a greater degree: IQ or Study Hours? Explain.

Mutating the dataset.

#So that gpa and IQ can be compared on similar scales, mutate the dataset gpa_iq so that the gpa is out of 100 points rather than 10. Call the new data set GPA100 and the new variable you create gpa_100)

Subsetting the data.

hint: subset function newdata <- subset(data, variable == ” “)

# using subset function
female <- subset(gpa, gender == "female")

# using subset function to create a male dataset with gpa data

Gender analysis

Now that you have a gpa dataset for females and one for males, write a question to compare the 2 genders, then create visualizations and describe what you see. Be sure that you visualization and analysis answer the question that you posed.
