F1 F2 F3 Help 10. Calculating the mean, the median, and the mode when scores are changed or removed Aa Aa Consider the following sample set of scores. Assume these scores are from a discrete distribution. 15 25 42 42 45 48 49 56 74 100 For the given data, the mean is-e--, the median is , and the mode is Suppose the score mean is median 100 in the data is mistakenly recorded as 1,000 instead of 100. For the sample with this error, the , the median is , and the mode is . The mean , the , and the mode da Suppose the score 100 in the original sample is inadvertently removed from the sample. For the sample with this score removed, the mean is , and the mode is t and the mode the median is The mean , , the median decreses CTASES emains-husame decren Flash Player WIN 26,0,0,151 Q3 3.34.1 © 2004-2016 Aplia.

Explanation / Answer

Answer to the question)
Original data

I used excel to find the three values

For mean , formula =average(a1:a10) , I got mean = 49.6

For mode , formula =mode(a1:a10) , Mode = 42

For median , formula =median(a1:a10) , Median = 46.5

.

If 100 is replaced by 1000 , we get

Mean = 139.6

Mode = 42

median = 46.5

.

Mean increases , mode remains same & median remains same

.

If 100 is removed from the dataset , we got only nine values , now

Mean = 44
Mode = 42

Median = 45

.

The value of Mean decreases, mode remains same & median decreases
