The Importance of Histrograms
Q: Why are histograms useful? What are some of the difficulties in creating histograms? Give some examples where a histogram is useful.
Here is some back ground info on a histogram:
A Histogram shows the frequencies, absolute or relative, that a specific variable takes on certain values. For example, if you rolled a die, you will get a number from 1 to 6. If you rolled it twenty-five times and count the number of times each number comes up you could generate a histogram of the data. Histograms are frequency charts and can be used for several purposes when solving quality problems.
