A frequency polygon is very similar to a

true
histogram
false
stem and leaf display
false
listing of raw data
Frequency polygons do not list the raw data, as stem and leaf plots do. Frequency polygons are very similar to histograms, except histograms have bars and frequency polygons have dots and lines connecting the frequencies of each class interval.
Check all that apply. Frequency polygons are better than histograms for:

true
false
showing the shape of the distribution
true
comparing distributions
false
revealing the exact values in a distribution
Frequency polygons are better at comparing distributions because two frequency polygons can be displayed in the same graph without obscuring each other. Both histograms and frequency polygons show the shape of the distribution. Neither necessarily reveals the exact values in a distribution.
Response times were generally shorter to the

true
large target
false
small target

Almost all of the times for the large target are below 750 msec., whereas there are many longer times for the small target.
