Select two interval-ratio level variables from the course data set: GSS2018
Use SPSS to generate the frequency distributions and descriptive statistics (using Frequencies and Descriptives ). Refer to module 2 that shows how to construct a five point summary
Construct the five point summary for each of the variables you have selected
Five point summary:
the sample minimum (smallest observation)
the lower quartile or first quartile
the median (the middle value)
the upper quartile or third quartile
the sample maximum (largest observation)
Discussion Post:
Present your two variables–explain what they are
Present the five point summary for each variable
Explain what the summary values indicate about each distribution
Synopsize the shape of the distribution in terms of skewedness and the degree of modality: Are the distributions relatively symmetrical or skewed? If skewed, what direction? Are the distributions strongly or weakly modal?
Respond to at least two other students’ posts with questions or comments about the variables they present
Go back to your post and review any responses posted by other students. Reflect on the responses to your post and consider posting a reply
