Question

find the median and mean of the data set below: 39, 48, 32, 47, 31, 38, 31 answer attempt 1 out of 3 median = mean =

Explanation:

Answer:

Median = 38
Mean = \(\frac{266}{7} = 38\) (Wait, no, let's recalculate: 31 + 31 + 32 + 38 + 39 + 47 + 48 = 312=62, 32=32, 38=38, 39=39, 47=47, 48=48. Sum: 62+32=94, 94+38=132, 132+39=171, 171+47=218, 218+48=266. Mean is 266/7 = 38? Wait, 738=266. Wait, but let's check the median: sort the data: 31, 31, 32, 38, 39, 47, 48. There are 7 numbers, so median is the 4th term, which is 38. Mean: 266 divided by 7 is 38. Wait, that's interesting. So median is 38, mean is 38. Wait, let's confirm: 31+31=62, 32=32 (total 94), 38=38 (132), 39=39 (171), 47=47 (218), 48=48 (266). 266/7=38. Yes. So:

Median = 38
Mean = 38
