Is the mean influenced more than the median by a few extreme scores at one end of the distribution?
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.

Is the median is always the point that is arithmetically exactly halfway between the highest and lowest scores of distribution?
false
How do you compute for the median class?
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.
What is a median score?
the sum of the scores divided by the number of scores submitted
The mean of 5 different scores is 10 what are the largest and smallest possible values for the median if all test scores must be whole numbers?
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).
What is another name for the median of a set of scores?

When the mean of a distribution of scores of measures is higher than the median the distribution would be?
The distribution is skewed to the right.
A lopsided distribution of scores in which the mean is much larger than both the mode and median is said to be?
skewed.
Is the median is always the point that is arithmetically exactly halfway between the highest and lowest scores of distribution?
false
Is median easily affected by extreme scores?
No. That is one of the reasons it is used in preference to the mean.No, it is not.
What is the median of Wednesday's test scores?
To find the median of Wednesday's test scores, first arrange the scores in numerical order from least to greatest, then select the middle value as the median. If there is an even number of scores, the median is the average of the two middle values.
How do you compute for the median class?
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.
Which of three three measures of central tendency is most affected by extreme scores?
Of the mean, median and mode the mean would be most affected.
The mean of a distribution of scores is the?
The mean of a distribution of scores is the average.
What does the median score mean?
the number that is in the middle of that particular set of numbers.
Do extremely high or low scores affect the value of the median?
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.
What is a median score?
the sum of the scores divided by the number of scores submitted
50 percent scores falling below median?
Yes. That is how the median is defined.
