Question

1. a dot plot shows most data points clustered between 5 and 15, with a few points trailing off below 0. how would you describe the shape of this distribution?

a. symmetric
b. bimodal
c. uniform
d. left - skewed

Explanation:

To determine the distribution shape:

• Symmetric: Data is evenly distributed around a center, no tail. This doesn't match as there's a tail below 0.
• Bimodal: Two distinct peaks. The data here has one cluster (5 - 15) and a tail, not two peaks.
• Uniform: Data is evenly spread across all values. Here, most data is in 5 - 15, so not uniform.
• Left - skewed: The tail is on the left (lower values, below 0 here), with most data on the right (5 - 15). This matches the description.

Answer:

d. Left - skewed
