Given the following cumulative frequency table, what is the mean of the distribution? value (x) cumulative frequency 2 0.05 4 0.40 6 0.45 8 0.70 10 1.00 μx = 2.7 μx = 4 μx = 6.5 μx = 6.8 μx = 20

For the given cumulative frequency table, mean is 6.8

Cumulative frequency table shown below,

Value (X)            Frequency (f)           cumulative frequency          X*f

 2                            0.05                            0.05                                  0.1

 4                            0.35                             0.4                                    1.4

 6                            0.05                            0.45                                  0.3

8                              0.25                            0.70                                  2

10                            0.3                                1.00                                 3

                                                                                                   Sum = 6.8

In cumulative frequency table , mean is the sum of table of, multiplication of value (X) and frequency (f).

Mean = ∑ X*f = 6.8

Therefore, mean

Use the cumulative frequencies to figure out what the individual frequencies would be. Check out the attached image for the table of x values with their corresponding frequency (f) values. Note how the partial sums add up to the cumulative frequency values.

Once you know the frequency f values, multiply each x and f pair together in each row. The column labeled "x*f" represents each product. Afterward, add up everything in the x*f column to get the final answer 6.8
