How can you tell if a histogram is skewed?

Back

A histogram is skewed if one tail is longer or fatter than the other. Right skewed has a longer right tail, while left skewed has a longer left tail.

Front

What does it mean if a histogram has a normal distribution?

Back

A normal distribution in a histogram is bell-shaped, indicating that most data points cluster around the mean, with symmetrical tails on either side.

Front

How do you find the range of data from a histogram?

Back

The range is found by subtracting the smallest data point from the largest data point represented in the histogram.

How can you compare two histograms?

Back

You can compare two histograms by examining their shapes, heights of bars, and overall distribution to see similarities or differences in data.

What does it indicate if a histogram has two peaks?

Back

A histogram with two peaks indicates a bimodal distribution, suggesting that there are two different groups or populations within the data.
