Group all the data into bins 0.2 of a grade point wide. It is very likely that small ranges of GPAs
would be easier to analyze than the individual GPAs would be. - (answers)You have a list of the
GPAs of 100 college graduates, precise to the nearest 0.001. You want to make a frequency
tables for these data. A good first step would be to
A bar graph would be most appropriate because the goal is to compare the numbers of visitors
that go to the attractions. A bar graph could do this because it uses a set of bars to represent the
frequency of each category. - (answers)You have a table listing ten tourist attractions and their
annual numbers of visitors. Which type of display would be most appropriate for these data?
Explain your reasoning.

your reasoning. - (answers)An example is ratings of
restaurants because they would be based on subjective opinions.
What is a histogram? - (answers)It is a bar graph for quantitative data.
Decide whether the following statements makes sense (or is clearly true) or does not make sense
(or is clearly false). Explain your reasoning.
I made a frequency table with two columns, one labeled "State" and one labeled "State Capitol."
- (answers)The statement does not make sense. In a frequency table, one of the columns lists the
frequency of each category, which is the number of data values in the category. The table
described in the given statement does not have this column.
Decide whether the following statements makes sense (or is clearly true) or does not make sense
(or is clearly false). Explain your reasoning.
, The relative frequency of B grades in our class was 0.3. - (answers)The statement makes sense.
Suppose there were 20 people in the class. If 6 received Bs, then the relative frequency of B
grades was StartFraction 6 Over 20 EndFraction
equals0.3.
Decide whether the following statement makes sense (or is clearly true) or does not make sense
(or is clearly false). Explain your reasoning.
The cumulative frequency of C grades in our class of 31 students was 50. - (answers)The
statement does not make sense because the frequency cannot be greater than the total.
Decide whether the following statement makes sense (or is clearly true) or does not make sense
(or is clearly false). Explain your reasoning.
Your pie chart must be wrong, because when I added the percentages on your wedges, they
totaled 124%. - (answers)The statement makes sense because pie charts are used primarily for
relative frequencies, so the total pie must always represent the total relative frequency of 100%.

Determine whether the following variable is qualitative or quantitative, and explain why.
Home prices in a small town - (answers)The 的”中文文章
variable is quantitative because price is a numerical
category.
Determine whether the following variable is qualitative or quantitative, and explain why.
Daily snowfall (in inches) during January in Syracuse, New York - (answers)The variable is
quantitative because inches are measurements.
Determine whether the following variable is qualitative or quantitative, and explain why.
The flavors of ice cream sold at a delicatessen - (answers)The variable is qualitative because
flavors are nonnumerical categories.
Use 4-point bins (96 to 99, 92 to 95, etc.) to make a frequency table for the set of exam scores
shown below. Include columns for relative frequency and cumulative frequency.
