which data set best approximates a normal distribution?
Answer
Brief Explanations:
A normal - distribution has a bell - shaped curve, symmetric about the mean. The data set with points forming a symmetric, bell - like shape around a central value best approximates it. Looking at the dot - plots, the one with the most symmetric distribution of points around a central value (around 40 - 50 in this case) is the best approximation.
Answer:
The top - right data set, as it has a symmetric distribution of data points around a central value, resembling the bell - shape of a normal distribution.
