As data distributions tasks can take various shapes and forms, always start with statistical reports as these may help you to find the answers that you require. See data distribution examples next to learn about the most suitable methodology for your particular case. There may be equations and a list of assumptions that are usually presented as word problems. If you have one in your school's textbook, compare it with the questions below and look for similarities. Since we are dealing with probability, do not forget to look into practice C Data distributions answers.
