For the set of numbers 2, 2, 4, 5 and 12, which of the following statements is true?
विकल्प
Mean = Median
Mean > Mode
Mean > Mode
Mode = Median
उत्तर
For the data 2, 2, 4, 5, 12 of 5 numbers, we have
`MEAN = (2+2+4+5+12)/5`
`=25/5`
= 5
`MEDIAN = ((5+1)/2)^(th) ` value
=3nd value
= 4
Since, 2 occurs maximum number of times, MODE=2
MEAN > MODE

A football player scored the following number of goals in the 10 matches:
1, 3, 2, 5, 8, 6, 1, 4, 7, 9
Since the number of matches is 10 (an even number), therefore, the median
= `(5^("th") "observation" + 6^("th") "observation")/2`
= `(8 + 6)/2` = 7
Is it the correct answer and why?
