Question

The amount of money (in $) spent on social events during a given week is given below for a sample of 10 college students. 45 49 50 50 68 70 71 72 300 500 Which measure of central tendency, mean or median, provides a more appropriate measure of center? Answer 10 Points I Tables Keypad Mean. The values are all basically similar to one another. Median. The values are all basically similar to one another. Mean. It is the primary measure of central tendency. Median. It is the case that some values are very different from the majority of values, so that the mean will be inflated above the majority of the data values.

Answer 1

1. Ans: 4th choice, note median is used when there are outliers and given data does have outliers. 2.True, because if n is odd, then median is eractly the middle value in the data set after sorting is done. 3. Ans : 7 and 8, note both are repeated thrice. 4.mean (13+33 + .. +41)/6 = 27.666, so now deviations – 14.666667,5.333333, 15.333333, -14.666667, -4.666667, 13.333333 so sum of deviations = 0(approx) so ans : 0 5. N ote 7 is repeated for highest no.of times i.e. 3 times. so Ans : 7 6. Since median (40th + 41st)/2; we know (n/2) = 40 5 n= 80 so ans : 80 7.ans : 46, 3 times repeated.

8. T= 219.5 n so ans 219500 correct choice : 3rd
