Math Test

This document contains a 10 question unit test on math in media. It covers key concepts like the different types of averages (mean, median, mode), samples vs populations, calculating a mean, ways math is used in media (social/economic trends, opinion polls, etc.), questions to consider when analyzing media's use of math, economic trends, why media doesn't always specify average type used, creating graphs from data, synonyms for validity, and why it's important to identify inaccurate math in media. The test evaluates understanding of basic mathematical analysis in relation to how numbers and data are presented and used in various media formats.

Social, economic trends; business conditions; opinion polls; census

5. What is one question you can ask yourself when encountering mathematical data
in the media? ​(1 point)
Answers may vary. Some possible answers could be: • Is this the
best mathematical model for the information being presented? ​•
What methods of mathematical analysis will best support the
position? ​• ​What variables should be included in the analysis to
strengthen the position? ​• ​Can mathematical models minimize the
appearance of important data? ​• ​Will percentages or fractions make a
more striking impression?

6. Which of these is NOT considered an economic trend? ​(1 point)


a. Newspaper
b. Network TV
c. Digital Ad revenue
