Question

In the data set below, what is the lower quartile?
12,45,51,55,56,70,70,72,81

Answer 1

Answer:

Lower Quartile = 48

Step-by-step explanation:

Since there are 9 numbers, the median is the 5th number (56)

Median is necessay for LQ

so, under the median are the numbers 12, 45, 51, 55

Median of these numbers is the mean of 45 and 51

45 + 51 = 96

96/2 = 48

LQ = 48

Hope this helps!
