Math Problem Statement
Consider the following sample set of scores. Assume these scores are from a discrete distribution. 20 25 25 36 42 56 69 74 98 100 For the given data, the mean is , the median is , and the mode is . Suppose the score 98 in the data is mistakenly recorded as 78 instead of 98. For the sample with this error, the mean is , the median is , and the mode is . The mean , the median , and the mode . Suppose the score 98 in the original sample is inadvertently removed from the sample. For the sample with this score removed, the mean is , the median is , and the mode is . The mean , the median , and the mode .
