which of the distributions is right skewed?
Answer
Explanation:
Step1: Recall right - skewed definition
A right - skewed distribution has a long tail on the right side. The bulk of the data is concentrated on the left side of the distribution.
Step2: Examine each histogram
For the first histogram, the bulk of the data is on the left and there is a long tail on the right. For the second histogram, the bulk is on the left but the tail on the right is not long enough to be considered right - skewed. For the third histogram, the data is more symmetric. For the fourth histogram, the data is symmetric as well.
Answer:
The first distribution (the one with data concentrated on the left and a long tail on the right) is right - skewed.
