Section 2.2

a researcher wanted to determine the number of televisions in households. he conducts a survey of 40 randomly selected households and obtains the data in the accompanying table. are these data discrete or continuous? explain

The given data is discreet because they can only have whole number values

The blank class limit is the smallest value within the class and the blank class limit is the largest value within the class

The lower class limit is the smallest value within the class and the upper class limit is the largest value within the class 😦

true or false? there is not one particular frequency distribution that is correct, but there are frequency distributions that are less desirable than others

The statement is true. any correctly constructed frequency distribution is valid. however, some choices for categories or classes give more information about the shape of the distribution

why shouldn't classes overlap when summarizing continuous data in a frequency or relative frequency distribution?

classes shouldn't overlap so there is no confusion as to which class and observation belongs

Construct a relative frequency distribution of the data.

relative frequency = frequency/ Total frequency

review question 6

review how math was performed

for the number of people per household in the United States, state, whether you would expect a histogram of the data to be bell-shaped, uniform, skewed left, or skewed right

skewed right
