Frequency Distributions and Histograms

Which of the following statements corresponds to a frequency distribution?

• a table that shows the number of times a data entry appears in a data set.

• a data set that shows the number of data entries that appear in a time.

• a conclusion drawn from a sample.

• the boundaries between two consecutive bars.

Observe the frequency distribution:

How many classes are there?

• 6

• 30

• 1-5

• 1-30
