CNSL 503 Module 2 Problem Set
1. What is a frequency table used for? A frequency table shows the number of times a
certain value occurs within a dataset, which is also
known as each value's frequency.
Frequency tables allow information to be more
easily organized.
2. What is one advantage of using a bar Bar charts can be used to display the frequency
chart over a pie chart? and relative frequencies of qualitative data.
Unlike pie charts, bar charts display the frequen-
cies for each category.
Bar charts are used more often to display the
results from studies with large datasets.
3. Name the types of graphs that can be Histogram

4. A frequency distribution polygon mea- A. Either interval or ratio scales

A. Either interval or ratio scales.
B. Only nominal scales.
C. Only ratio scales.
D. Either nominal or ordinal scales.
