The box plot was created by using which pieces of data? A) an upper quartile of 56 and a median of 50 B) a lower quartile of 56 and a median of 50 C) a median of 56 and a lower quartile of 50 D) a median of 56 and an upper quartile of 50

A) an upper quartile of 56 and a median of 50

Step-by-step explanation:

Hello!

The lower and upper ends "box" from the box and whiskers plot is determined by the first (Q₁) and third (Q₃) quartiles of the data set and the line inside the box marks the median or second quartile of the sample (Q₂)

The length of the whiskers of the diagram is determined by the minimum value (left whisker) and the maximum value (right whisker)

If you observe the graphic:

Q₁= 42

Q₂= 50 (Median)

Q₃= 56

Min= 38

Max= 66

The box is delimited by a lower quartile of 42 and an upper quartile of 56, with a median 50, the least observation is 38 and the highest observation is 66.

The correct choice is A.

I hope this helps!
