There is one outlier that indicates an unusually large number of cars were in the parking lot that day.
There are two outliers that indicate an unusually large number of cars were in the parking lot those two days.

Answer 1

From the data, it looks like the numbers for all of the days (with one exception) falls between 7 and 14, hovering around 10
Are you able to see the outlier? And is it much larger or much smaller compared to the other entries?

Answer 2

it is much larger

Answer 3

I would agree! Just to make sure we're on the same page, what number are you looking at as the outlier?

Answer 4

I think its C

Answer 5

Yup, I'm pretty sure you're right. The one day, with 27, is more than twice as large as almost all of the other entries, so it's definitely an outlier
