How do you work out frequency from a frequecny density histogram?
class width times frequency density gives you the frequency
How do you work out the frequency for a histogram?
Frequency Density multiplied by the class width
What does the vertical axis of a histogram measure?
The y axis on a histogram represents the frequency density.
What does the height of a bar in a histogram represent?
The frequency density. That is, the frequency divided by the class width.
Cumulative frequency histogram?
They can be created but, because histograms are generally plots of frequency density, rather than frequency, they are likely to be quite difficult to interpret.
How do you find the frequency and frequency density on a histogram when you are only given the class width?
To calculate the frequency density we will simply divide the frequency by the class width.

What the difference between histogram and a bar graph?
A bar graph cannot have classes with different width. The height of a bar graph represents the frequency attributed to that class whereas in a histogram the area of a "bar" is proportional to the frequency, the height represents the frequency density.
What represents frequency on a histogram?
y axis represents frequency ona histogram
What is the difference between bar and histogram?
Bars are for single values or classes with uniform width, and the height of each bar is the frequency. In a histogram, the classes are of different width and the heights are proportional to the frequency density. The frequency, itself, is given by the area of the "bar" above the class.
How do you create a percentage frequency histogram?
what is the difference between a regular histogram and a percent frequency polygon
What is a histogram for?
A histogram is when the bars are touching and it graphs what you have on your frequency table.
What is a histogram used for?
A histogram is when the bars are touching and it graphs what you have on your frequency table.
