A frequency distribution shows the number of elements in a data set that belong to each class. QUESTIONFor a relative frequency distribution, relative frequency is computed as _____.ANSWERA.) c. 2% class 1 = F, E, L (or L, E, F) class 2 = L, F, E (or E, F, L) class 3 = F, L, E (or E, L, F) B.) c. the total number of elements in the data set The relative frequency can be calculated using the formula fi=fn f i = f n , where f is the absolute frequency and n is the sum of all frequencies. D. The "5 to the k rule" can be applied. 75% C. 50% D. 25%. A group of 100 students was surveyed about their interest in a new International Studies program. a. D. frequency divided by the total frequency . The relative frequency for a class is computed as: A. class width divided by class interval. Which of the following is the correct relative frequency for McDonalds? Which of the following is the correct frequency distribution? 0 votes . c. 54 Dummies has always stood for taking on complex concepts and making them easy to understand.

Michael's Compute-All, a national computer retailer, has kept a record of the number of laptop computers they have sold for a period of 80 days. Mellow Mushroom Luppi's Pizza Hut A tabular summary of a set of data showing the fraction of the total number of items in several classes is a a. frequency distribution b. relative frequency distribution c. frequency d. cumulative frequency distribution ANSWER: b 4. 9. c. 0.4 The relative frequency can be calculated using the formula fi=fn f i = f n , where f is the absolute frequency and n is the sum of all frequencies. One technique is to draw a histogram for the data and see if it is approximately bell-shaped. For example, let's say we have a table that looks like this: 75 8 84 45 For the row relative frequencies we divide each data point by the sum of the data in that row: 75(75 + 8) 8(75 + 8) 84(84 + 45) 45(84 + 45) A student was interested in the cigarette smoking habits of college students and collected data from an unbiased random sample of students. For example, suppose a sample found that, in a survey, 10 people said they had a pet dog. Frequency is also the theoretical number of ways an event can occur. The cumulative relative frequency of a class interval is the cumulative frequency divided by the sample size. a. If we want to condense the data into seven classes, what is the most convenient class interval?

A) Relative frequency of the picked candy to be one of her favorites: (Frequency of yellow + Frequency of red candy)/ 20 = 12/ 20 = 60%. A histogram looks similar to a bar chart but it is for quantitative data. c. line of zero intercept These figures are referred to as a(n) __________. The relative frequency for a class represents the. For example, suppose that a frequency distribution is based on a sample of 200 supermarkets. in financial engineering from Polytechnic University.
