The score obtained in a mathematical quiz by 5 boys are 4,6,3,6,7 and 4 girls are 6,3,4,7 calculate the mean median mode range

To find the mean, add up all the scores and divide by the total number of scores:

Mean = (4 + 6 + 3 + 6 + 7 + 6 + 3 + 4 + 7) / (5 + 4) = 46 / 9 = 5.11 (rounded to two decimal places)

To find the median, first arrange all the scores in ascending order:

3, 3, 4, 4, 6, 6, 6, 7, 7

The median is the middle value, which in this case is 6.

To find the mode, identify the value or values that occur the most frequently. In this case, the mode is 6 because it appears three times, which is more frequent than any other value.

To find the range, subtract the lowest score from the highest score:

Range = 7 - 3 = 4
