How Do You Make A Frequency Chart And Determine Frequency In Statistics?
If you are asked to determine the frequency of something in statistics, it doesn’t just mean that you should just count out the number of times something occurs. You’ll often be asked to make a frequency distribution chart. If you are looking for a more complex distribution chart using classes, you’ll find a link in the “resources’ section to another EHow article that explains classes. Make a chart for your data. For this example, let’s say you’ve been given a list of twenty blood types for incoming emergency surgery patients (A,O,A,B,B,AB,B,B,O,A,O,O,O,AB,B,AB,AB,A,O,A). On the horizontal axis, write “frequency(#)” and “percent(%)”. On the vertical axis, write your list of items. In this example, we have four blood types: A, B, AB, and O. Count the number of times each item appears in your data. In this example, we have A (5), B (5), O (6) and AB (4). Write those in the “number” column: this is your frequency. Use the formula %=(f/n)*100 to fill in the next two columns. In this exampl
