Daniela made her error on step 3 because it says:
"Find the ratio of the differences of the means compared to the mean absolute deviation.
She didn't find the difference between the today and last week means. She just put the mean as a whole.
First you find the median, by taking 893+954 and dividing the sum of those two numbers by 2. The median is 923.5. Then you take and find the median of the numbers before the median which is 513. That is your lower quartile. Then you find the median of the numbers below the median, which is 1038. That is your upper quartile. The interquartile range is your upper quartile minus your lower quartile.
Therefore, your answer would be:
Median- 923.5
Lower Quartile- 513
Upper Quartile- 1038
Interquartile Range- 525
the answer is A.
