Due Sunday 10.01.17 at 11:00 PM Attempts: 3. Measures of central location- Mean, median, and mode Consider the following set of sample data Score: 15 Aa Aa 2 30 32 38 38 45 50 64 72 100 the given data, the mean is , the median is and the mode is Suppose the observation 2 in the data is mistakenly recorded as 28 instead of 2. For the sam ple with this error, the mean is median the median is , and the mode is The mean , the and the mode Suppose the observation 2 in the original sam ple is inadvertently removed from the samplo. For the sam ple with this observation removed, the mean is , the median is , and the mode is The mear , the median , and the made arated 8 57 AM KARD

Explanation / Answer

for above:

therefore mean =47.1

median =(n+1)/2 th value =5.5 th value =(38+45)/2 =41.5

mode =38 as it appears maximum times in data .

2)

for replacement of 2 with 28:

mean =49.7

median =(n+1)/2 th value =5.5 th value =(38+45)/2 =41.5

mode =38 as it appears maximum times in data

3)for 3rd condition

mean =52.11

median =(n+1)/2 th value =5 th value =45

mode =38 as it appears maximum times in data

2 30 32 38 38 45 50 64 72 100 total 471 mean=total/10 47.10
