Answer to Question 1

A histogram graphically displays class intervals as well as class frequencies. A bar chart displays the frequencies for a set of categories or classes. Histograms are appropriate for quantitative data, while bar charts are better for qualitative data. Adjacent rectangles in the histogram share a common side while those in the bar chart have a gap between them.

Answer to Question 2

The guidelines for constructing a frequency distribution are:
a . The set of classes must be mutually exclusive, with no overlaps.
b. Set of classes must be exhaustive.
c. If possible the classes should have equal widths.
d. In general, about 5 to 15 classes will be suitable.
e. When possible, class widths should be round numbers.
f. Avoid using open-end classes.

The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
