Histograms

In this lesson, we will learn how to find frequency density for grouped frequency distributions with unequal class intervals and use them to plot a histogram

In this lesson, we will learn how to complete a frequency table from a histogram, use a histogram and a known frequency to find the scale on the vertical axis and subsequently all the other frequencies.

In this lesson, we will learn how to use a histogram to estimate the median, quartiles or frequencies using parts of bars

In this lesson, we will learn how to find probabilities from a histogram by finding the frequencies represented by each bar and the vertical scale.
