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.
The 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.
Frequency is measured using a unit called the hertz to denote the number of cycles a wave produces in a second. The number of hertz is calculated by dividing the number of repeat cycles by the length of time in seconds.
Full Answer >The unit for frequency in the International System of Units is hertz, which is abbreviated as Hz. One hertz is defined as a frequency of one cycle per second.
Full Answer >The most common unit used to measure frequency is hertz (Hz), which refers to cycles per second; however, there are some other ways to measure frequency, such as revolutions per minute (RPM) for a motor or beats per minute (BPM) for a person's heartbeat. Frequency refers to how often an event occurs in a specific time frame, such as a minute or second.
Full Answer >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.
