Given below is the data of the ages of various children.
What is the difference between the mean and mode of the ages? |
1.5 1 2.5 2 |
1.5 |
Total number of children = 17 + 16 + 16 + 17 + 19 + 15 = 100 Mean of age = \(\frac{ 6×17+7×16+8×16+9×17+10×19+11×15 }{100}\) = \(\frac{ 102+112+128+153+190+165 }{100}\) = \(\frac{ 850 }{100}\) = 8.5 Mode = 10 ( Because 10 hase highest frequency i.e. 19 ) Difference b/w mean and mode = 10 - 8.5 = 1.5 |
