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.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
