Question 0

Discrete data

Answer 0

data that can take on a countable number of possible values

Question 1

Frequency Distribution

Answer 1

A summary of a set of data that displays the number of observations in each of the distribution’s distinct categories or classes

Question 2

Relative frequency

Answer 2

the portion of total observation that are in a given category. Relative frequency is computed by dividing the frequency in a category by the total number of observations. The relative frequencies can be converted to percentages by multiplying by 10

Question 3

Continuous data

Answer 3

Question 4

Mutually exclusive classes

Answer 4

classes that do not overlap so that a data value can be place in only one class

Question 5

All-Inclusive classes

Answer 5

A set of classes that contains all the possible data values

Question 6

Equal-width classes

Answer 6

the distance between the lowest possible value and the highest possible value in each class is equal for all classes

Question 7

Class width

Answer 7

the distance between the lowest possible value and the highest possible value for a frequency class

Question 8

Class boundaries

Answer 8
