the relative frequency for a class is computed as

Identify the class boundaries of the first class. For example, you calculate the relative frequency of prices between $3.50 and $3.74 as 6/20 to get 0.30 (30 percent). The relative frequency for a class is computed as the class A. width divided by class interval. Outside of the academic environment he has many years of experience working as an economist, risk manager, and fixed income analyst. c. 1 Answer. Which of the following is the correct frequency distribution? Which of the following is the correct relative frequency for McDonalds? When missing values are treated as valid values, it causes the "Valid Percent" columns to be calculated incorrectly. Fifteen percent of the students in a school of Business Administration are majoring in Economics, 20% in Finance, 35% in Management, and 30% in Accounting. b. quantitative data A histogram looks similar to a bar chart but it is for quantitative data. The relative frequency of a class is computed by . a. one B. class midpoint divided by the class frequency. Number of hours Frequency a. one for the first class . d. 34.5, Exhibit 2-3 B midpoint divided by the class frequency. A frequency distribution shows the number of elements in a data set that belong to each class. McDonalds 6, Friday's 1, Pizza Hut 3, Mellow Mushroom 1, Luppi's 2, Taco Bell 2 Transcribed image text: What is the value of X in the following relative frequency distribution? 60 - 79 20 100% For the supermarket example, the total number of observations is 200. This turns out to be 800 in New York and 200 in Connecticut. The number of students working 19 hours or less b. dividing the frequency of the class by the midpoint.
