Yes. The mean uses the actual value of each observation.
The value(s) of only the middle observation (or pair of middle observations) is required for the median. For all other observations, the median is concerned only with whether it is larger or smaller than it is.
false
The median is the number in the middle. Arrange all the scores from smallest to biggest and the middle on is the median if there is an odd number of scores. If there is an even number of scores, find the mean of the two middle numbers and that is the median.
the sum of the scores divided by the number of scores submitted
If scores of zero are permitted, the lowest median is 2 as in (0,1,2,3,44) and the highest median is 10 as in (8,9,10,11,12). If a zero score is not permitted, then the lowest median is 3 as in (1,2,3,4,40).
q2
The distribution is skewed to the right.
skewed.
false
No. That is one of the reasons it is used in preference to the mean.No, it is not.
The mean of a distribution of scores is the average.
Of the mean, median and mode the mean would be most affected.
The median is the number in the middle. Arrange all the scores from smallest to biggest and the middle on is the median if there is an odd number of scores. If there is an even number of scores, find the mean of the two middle numbers and that is the median.
the number that is in the middle of that particular set of numbers.
No, extremely high or low values will not affect the median. Because the median is the middle number of a series of numbers arranged from low to high, extreme values would only serve as the end markers of the values.
the sum of the scores divided by the number of scores submitted
Yes. That is how the median is defined.
If scores of zero are permitted, the lowest median is 2 as in (0,1,2,3,44) and the highest median is 10 as in (8,9,10,11,12). If a zero score is not permitted, then the lowest median is 3 as in (1,2,3,4,40).
