Tia, Bill, Kay, and Marco counted the number of fireflies they saw each day for a week in the summer. They each put their numbers in order from least to greatest. Tia: 9, 12, 15, 18, 21, 24, 27 Bill: 3, 6, 8, 18, 20, 21, 22 Kay: 14, 15, 16, 18, 24, 27, 32 Marco: 2, 6, 10, 14, 18, 22, 26 Whose data is skewed left? A. Tia's data B. Bill's data C. Kay's data D. Marco's data witch is closest to the right answer
To determine which data is skewed left, we need to look for a dataset that has a tail extending to the left and a concentration of values towards the right.
Looking at the data:
Tia's data: 9, 12, 15, 18, 21, 24, 27
Bill's data: 3, 6, 8, 18, 20, 21, 22
Kay's data: 14, 15, 16, 18, 24, 27, 32
Marco's data: 2, 6, 10, 14, 18, 22, 26
We can see that Tia's data has a relatively equal distribution of values throughout the dataset without a strong tail to the left or right. Bill's data also appears to have a relatively equal distribution with a slight tail to the left. Kay's data has a similar distribution to Tia's data, without a strong tail. Marco's data has a concentration of smaller values towards the left, with a tail to the right.
Therefore, the dataset that is skewed left is Marco's data.
The correct answer is D. Marco's data.
