Class interval width calculator
WebJun 7, 2024 · Add the class interval width to find the upper limit of the first interval and the lower limit of the second variable. Keep adding the interval width to calculate more class intervals until you exceed the highest value. Create a table with two columns and as many rows as there are class intervals. WebSo the class width is 2.28 (round up to the next value, in hundredths). Here's the frequency distribution. I have also included the class boundaries, needed for the histogram, and the midpoints. The boundaries and midpoints should not be rounded off. These midpoints work out to a value in the hundredths; sometimes you need thousandths.
