Question

For the following data:

 

0.1   2.5.  2.6.  5.1   5.3.  6.7.  7.1

7.3.  7.5.  7.5.  8.9.  9.9.  10.1.  11.3

11.7.  12.5.  12.8.  14.1.  15.0.  17.5.  18.9

19.8.  21.7. 24.4.  24.9

 

a.  Construct a frequency distribution

b.  What is the median of the table

c.  What is the mean of the data

d.  What is the mode of the data

Answer 1

The median is 10.1, the 13th of 25 statistics shown

 

THe total is 285.2

 

The mean average is 11.408

 

the mode is 7.5, which occurs twice

 

For a frequency distribution, you will have to make a hash table,

using ranges and intervals. For example, a balanced table will have:

    5 stats no larger than 6;

    5 stats between 6 and 8

    5 stats between 8 and 12;

   5 stats between 12 and 18;

  5 stats between 18 and 25
