उत्तर
In the class intervals 10 – 20, 20 – 30, the number 20 is included in 20 – 30.
Explanation:
Since, the class interval 10 – 20 is the first interval of frequency distribution and 20 – 30 is the next one but the number 20 is present in both intervals.
We know that, the presence of 20 in the interval 10 – 20 is not fully 100% while in the next interval 20 – 30, presence of it fully 100%.

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?
