The required 1) Mean = 18.5, 2) Median = 18, 3) Mode = 0, 4)Range = 21.
20, 17, 10, 31, 25, 18, 12 for a given series mode, range, mean, and median to be determined.
What are mode, range, mean, and median?
Mean is defined as the average of total values.
Mode is defined as the number with the greatest frequency.
Median is defined as when a number arrange in sequence then most mid number is the median.
The range is the difference between the largest and smallest number.
Mean = [tex](20+17+10+31+25+18+12)/7\\[/tex]
Mean = 18.5
Median, arranging the number in ascending order.
10,12,17,18,20,25,31
Median = (n+1)/2 th term
= (7+1)/2
= 4th term
Median = 18
Mode, Clearly there is no repeating number so frequency is zero implies Mode = 0
Range = 31 -12
= 21
Thus, the required 1) Mean = 18.5, 2) Median = 18, 3) Mode = 0, 4)Range = 21.
