Question

1. what does a histogram with bars decreasing in height from left to right indicate?

a. left - skewed distribution
b. uniform distribution
c. right - skewed distribution
d. normal distribution

Explanation:

To determine the answer, we analyze each option:

• Option a: A left - skewed (negatively skewed) distribution has a long tail on the left, and the bars would increase from left to right (more data on the right). So this is incorrect.
• Option b: A uniform distribution has bars of approximately equal height since all values have roughly the same frequency. So this is incorrect.
• Option c: A right - skewed (positively skewed) distribution has a long tail on the right. In a histogram, this means that the bars decrease in height from left to right (most of the data is on the left side). This matches the description in the question.
• Option d: A normal distribution is symmetric, with the highest bar in the middle and bars tapering off on both sides. So this is incorrect.

Answer:

c. Right - skewed distribution
