How do you determine the height of a bar in a histogram?

Back

The height of a bar in a histogram represents the frequency (count) of data points that fall within the corresponding bin.

What does it mean if a histogram is skewed to the right?

Back

A right-skewed histogram indicates that the majority of data points are concentrated on the left side, with fewer high values stretching the tail to the right.

Front

What does it mean if a histogram is symmetric?

Back

A symmetric histogram indicates that the data is evenly distributed around a central value, with similar frequencies on both sides.

How can you identify the mode from a histogram?

Back

The mode can be identified as the bin with the highest bar (frequency) in the histogram.

How do you interpret the width of the bins in a histogram?

Back

The width of the bins affects the granularity of the data representation; narrower bins provide more detail, while wider bins provide a more general overview.

What is the difference between a histogram and a bar graph?

Back

A histogram displays the distribution of continuous data, while a bar graph represents categorical data with distinct categories.

How can you find the total number of data points from a histogram?

Back

The total number of data points can be found by summing the heights of all the bars in the histogram.
