A frequency distribution shows the frequency of the data elements it represents

(a) A frequency distribution

To do this, we make use of a table that has the following columns

  • SN
  • Software
  • Frequency
  • Relative frequency

Using the given dataset, the frequency distribution is:

SN  Software Frequency Relative frequency

1      Excel         34                      48.6%

2    Minitab       17                       24.3%

3     SAS            3                        4.3%

4     SPSS          4                        5.7%

5      Other        12                      17.1%

(b) Present the frequency distribution on a chart

See attachment for the histogram that represents the frequency distribution

(c) Interpret the chart

From the chart, we have the following highlights:
