Question

Find the mean, median and mode of the following data:
classes: 0-50 50-100 100-150 150-200 200-250 250-300 300-350
Frequency: 2 3 5 6 5 3 1

Answer 1

done.

hope it helps you.....!

Answer 2

Mean = 169

Median = 175

Mode = 157

Step-by-step explanation:

Let us assume A = 20.

Please refer to the attached picture for the table.

classes: 0-50 50-100 100-150 150-200 200-250 250-300 300-350

midpoint(x) : 25    75   125    175  225    275    325

   Frequency: 2     3     5     6     5      3     1

Cumulative f : 2     5     10    16    21     24    25

fx          : 50    225   625   1050  1125   825   325

Mean = sum of fx / sum of f = 4225 / 25 = 169

Median = n + 1/2 = 25 + 1/2 = 13th item = 175

Mode = 3 * media - 2*  mean

    = 3 * 169  - 2 * 175

    = 507 -350

    = 157
