To find the mean of the absolute differences, we first need to find the mean of the given numbers:
(141+330+292+198+263+224+149+121+223+125+126+48+111+327+238) / 15 = 204.6
Next, we find the absolute difference between each number and the mean and add them up:
|141-204.6| + |330-204.6| + |292-204.6| + |198-204.6| + |263-204.6| + |224-204.6| + |149-204.6| + |121-204.6| + |223-204.6| + |125-204.6| + |126-204.6| + |48-204.6| + |111-204.6| + |327-204.6| + |238-204.6|
= 63.6 + 125.4 + 87.4 + 6.6 + 58.4 + 19.4 + 55.6 + 83.6 + 18.4 + 79.6 + 78.6 + 156.6 + 93.6 + 122.4 + 122.4 = 1151.2
Finally, we divide the sum by the number of numbers (15) to find the mean of the absolute differences:
1151.2 / 15 = 76.747.
Therefore, the mean of the absolute differences between each number and the mean of these numbers is approximately 76.747.
(141+330+292+198+263+224+149+121+223+125+126+48+111+327+238) / 15 = 204.6
Next, we find the absolute difference between each number and the mean and add them up:
|141-204.6| + |330-204.6| + |292-204.6| + |198-204.6| + |263-204.6| + |224-204.6| + |149-204.6| + |121-204.6| + |223-204.6| + |125-204.6| + |126-204.6| + |48-204.6| + |111-204.6| + |327-204.6| + |238-204.6|
= 63.6 + 125.4 + 87.4 + 6.6 + 58.4 + 19.4 + 55.6 + 83.6 + 18.4 + 79.6 + 78.6 + 156.6 + 93.6 + 122.4 + 122.4 = 1151.2
Finally, we divide the sum by the number of numbers (15) to find the mean of the absolute differences:
1151.2 / 15 = 76.747.
Therefore, the mean of the absolute differences between each number and the mean of these numbers is approximately 76.747.
