To calculate relative frequency, get the total of the provided data, and divide each frequency by the answer. The total figure is found by adding every number in the provided classes.
Know MoreThe class of the data is mostly represented by letters. The frequency is the set of numbers under each class. For instance, a particular class of data would show that 10 students got grade A, 12 students got grade B, 21 students got grade C, 15 students got grade D, and 12 students had grade E.
Add the number of students to find the total attendance during the test. Therefore, by adding 10+12+21+15+12, you get 70, which is the total attendance.
Pick each number in the class, and divide it by the total attendance. Hence, 10/70= 0.14, 12/70= 0.17, 21/70= 0.3, 15/70= 0.21 and 12/70= 0.17. The numbers in decimal points are your relative frequencies. Convert them into percentage form by multiplying them by 100.
From your answer, you realize that 14 percent of students got grade A, 17 percent got grade B, 30 percent got grade C, 21 percent got grade D, and 17 percent got grade E. If the question does not need the answer in percentage form, then leave it as a decimal or whole number. Use this example to calculate the relative frequency of other statistical data.
In theory, a 5-gallon jug filled completely with $100 bills can contain a total of $980,000. If the jug is filled with $1 coins, it could hold a total of $33,333. The amount varies widely depending on the combination of coins and bills used to fill the jug.
Full Answer >To convert kilograms to pounds, multiply 24 kilograms by the conversion rate of 2.2046 to determine the number of pounds, which equals a total of 52.9. You need a calculator, a pencil and paper or a website that will do the conversion for you.
Full Answer >Cumulative relative frequency is a statistical calculation figured by adding together previously tabulated relative frequencies that makes a running total along a frequency table, according to Connexions. For instance, the first relative frequency of an occurrence is two out of 20 and the second relative frequency is five out of 20. The two frequencies are added together to make seven of 20, or 0.35 for a cumulative relative frequency.
Full Answer >To express 155 pounds in kilograms, you must simply multiply 155 x 0.454 to arrive at the answer of 70.37 kilograms. This works because 1 pound is equal to 0.454 kilograms.
