This module presents students with a number of problems related to statistical sampling and data. In particular, students are asked to demonstrate understanding of concepts such as frequency, relative frequency, and cumulative relative frequency, random samples, quantitative vs. qualitative data, continuous vs. discrete data, and other key terms related to sampling and data.
For each item below:
Identify the type of data (quantitative - discrete, quantitative - continuous, or qualitative) that would be used to describe a response.
Give an example of the data.
Number of tickets sold to a concert
Amount of body fat
Favorite baseball team
Time in line to buy groceries
Number of students enrolled at Evergreen Valley College
Most–watched television show
