A die is a cube that has a different number of spots (1 to 6) on each ofits sides. Imagine that you have N dice in all and that X;i represents the number of spots on the ith side of the jth die. Write an expression using a double summation (including the indexes) to indicate the sum of all the spots on all of the dice. 5. Perform the summation indicated by the expression you wrote in exercise 4 for N = 10. ' Concepts Continuous versus discrete scales 1. Double subscripts can be used to indicate that a collection of variables differs along two dimensions.
The score with the highest frequency is the mode of the distribution. :A 30 Chapte.. 2 • Frequency Tables, Graphs, and Distributions 3. It is easy to create a cumulative frequency (cf) distribution from a simple frequency distribution: The cf entry for each score is equal to the frequency for that score plus the frequencies for all lower scores. ) The cf entry for the highest score must equal ~ f = N (the total number of scores in the group). 4. To convert a simple or cumulative frequency distribution to a relative or cumulative relative distribution, divide each entry by N.
Create a simple frequency table to display these results. Add columns for cf, rf, crf, and cpf. a. How many students obtained a perfect score? What proportion does that represent? b. What score is closest to the 50th percentile? c. What is the percentile rank of a student who scored a 5? Of a student who scored a 9? -32 Chaptet< 2 • d. What proportion of the students scored 9 or more? e. Draw a frequency polygon to represent the data. 6. Draw a cumulative percentage polygon (ogive) to represent the data in Exercise 3.
