Each bars height represents a certain number. Read all these heights and add the numbers together. Then take each individual bars value divide that by the total and multiply by 100 to get percentages.

Explain why the discrete histogram equalization technique does not generally yield a flat histogram?

All that histogram equalization does is remap histogram components on the intensity scale. To obtain a uniform (­at) histogram would require in general that pixel intensities be actually redistributed so that there are L groups of n=L pixels with the same intensity, where L is the number of allowed discrete intensity levels and n is the total number of pixels in the input image. The histogram equalization method has no provisions for this type of (arti®cial) redistribution process.


What graph can you always find measures of central tendency?

You can always find measures of central tendency, such as the mean, median, and mode, in a histogram. A histogram visually represents the distribution of data and allows for easy identification of central tendencies. Additionally, these measures can also be found in other graphs like box plots and bar charts, but histograms are particularly effective for continuous data.


What are the ranges of data in a histogram?

They are the class boundaries.


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 type of scores represents a histogram?

A histogram represents the distribution of scores in a dataset by organizing them into equally spaced intervals or bins along the horizontal axis, and displaying the frequency or count of scores within each bin on the vertical axis. The scores on the horizontal axis could be any type of numerical data, such as test scores, heights, or ages.
