To find the third quartile (Q3), we need to first find the median of the dataset, which is the middle value when the numbers are arranged in ascending order.
Arranging the dataset in ascending order:
45.5, 46.9, 47.2, 47.5, 48.1, 49.7, 52.1, 53.3
The median of this dataset is the average of the two middle numbers:
(47.5 + 48.1) / 2 = 47.8
So, the third quartile (Q3) is 47.8.
Therefore, the correct answer is c) 47.8.
identify the third quartile in the following dataset 53.3 46.9 48.1 49.7 52.1 47.5 47.2 45.5 a 47.05 b 53.3 c 47.8 d. 50.9

find the range of the given data set 51 13 98 42 76 28
To find the range of a data set, you subtract the minimum value from the maximum value.
Given data set: 51, 13, 98, 42, 76, 28
Minimum value = 13
Maximum value = 98
Range = Maximum value - Minimum value
Range = 98 - 13
Range = 85
Therefore, the range of the given data set is 85.
Given data set: 51, 13, 98, 42, 76, 28
Minimum value = 13
Maximum value = 98
Range = Maximum value - Minimum value
Range = 98 - 13
Range = 85
Therefore, the range of the given data set is 85.
