The box plots show lauren’s chemistry scores and her biology scores. chemistry biology lauren used the steps below to determine the differences in the medians and the interquartile ranges. step 1 find the median for chemistry: 80 find the median for biology: 70 step 2 find the difference in the medians: step 3 find the interquartile range for chemistry: find the interquartile range for biology: step 4 find the difference in the interquartile ranges: lauren determined that the difference in the medians is greater than the difference in the interquartile ranges. which explains lauren’s error?
a) lauren made her first error in step 1 because the median is 85 for chemistry and 80 for biology.
b) lauren made her first error in step 1 because the median is 60 for chemistry and 60 for biology.
c) lauren made her first error in step 3 because she should have used for chemistry and for biology.
d) lauren made her first error in step 3 because she should have used for chemistry and for biology.

Explanation:

Without the diagram illustrating the scores for the subjects, it is not possible to give exact values, however the process of finding each answer can be explained.

The options are related to errors made in steps 1 and 3. For step 1:

Finding the median is simply reading off the graph/diagram. If you wish to calculate the value on your own, you take the "middle value". For example, if the scores are 60, 70 and 80, the median value would be the one in the middle (70).

For step 3:

Calculating the interquartile range is done by taking the value for the 3rd quartile, and subtracting the value for the 1st quartile. The difference between the values is known as the interquartile range.

Lauren made her first error in step 3 because she should have used 90 minus 55 = 35 for chemistry and 90 minus 50 = 40 for biology.

Explanation:

i know this because in order to find the answer you must subtracts the highest number from the lowest
