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.
Magnification is the ratio between an object's apparent size, usually seen through some sort of lens apparatus, and the object's actual size. Total magnification refers to the amount of magnification an apparatus has when taking all of the optics involved in the apparatus into account.
Full Answer >To convert mils to millimeters start by multiplying the mils value by 127, then divide the answer by 5,000, and finally, label the figures to make the answer more precise. Mils is a distance measurement used in the fields of engineering and manufacturing. Converting mils to millimeters allows numbers to be more understandable to the general public.
Full Answer >The answer to how many CCs equal one horsepower can only be estimated at 1HP per 15-25 CCs. There are too many variables to enable an exact calculation.
Full Answer >Litres are a measurement of volume, while tons are a unit of weight, so the answer varies depending on the density of the substance being measured. The denser the substance, the less of it is needed to reach a ton.
