1.
In a survey of 100 people, the sports preferred by them are shown in the table.
Which type of graph is appropriate to represent the data?
Favorite Sports
 Sports Athletics Soccer Tennis Baseball Golf Number of people 15 30 20 25 10 a. bar graph b. stem-and-leaf plot c. circle graph d. line graph

#### Solution:

A stem-and-leaf plot is an arrangement of digits that is used to display and order numerical data.

Circle graphs are the best type of graphs for showing the relative proportions of different categories to each other and to the whole.

A line graph shows the relationship between the dependent and independent variables when both are numerical and the dependent variable is a function of the independent variable.

A bar graph is appropriate for comparing different trials or different experimental groups.

The bar graph compares preference of sports among people.

Therefore, bar graph is the appropriate type of graph to represent the given data.

2.
Ken conducted a survey on the favorite sport of the students in the fifth and the sixth grade. Which of the graphs would he use to show the data? a. line graph b. stem-and-leaf plot c. double bar graph d. circle graph

#### Solution:

Line graphs, suitable for showing change in the data over a period time.

Stem-and-leaf plots, suitable for showing numerical data in order.

Circle graphs, suitable for showing data that are parts of a whole.

Double line graphs suitable for comparing two sets of data.

The data on favorite sport of the students of fifth grade and sixth grade represents two sets of comparing data.

The most appropriate graph for Ken′s data is double bar graph.

3.
The table shows the modes of transportation of employees of a company. Identify the most appropriate graph for the data.  a. stem-and-leaf plot b. bar graph c. line plot d. circle graph

#### Solution:

A bar graph is appropriate for comparing different trials or different experimental groups.

A stem-and-leaf plot is an arrangement of digits that is used to display and order numerical data.

A line plot is usually used when there is one group of data.

Circle graphs are the best type of graphs for showing the relative proportions of different categories to each other and to the whole.

As the data is given in percents, a circle graph would be appropriate.

4.
The data shows the ages of 25 residents of a community in Georgia. Which of the following graph would you use to show the data?  a. circle graph b. stem-and-leaf plot c. bar graph d. line graph

#### Solution:

A bar graph is appropriate for comparing different trials or different experimental groups.

A line graph shows the relationship between the dependent and independent variables when both are numerical and the dependent variable is a function of the independent variable.

Circle graphs are the best type of graphs for showing the relative proportions of different categories to each other and to the whole.

A stem-and-leaf plot is an arrangement of digits that is used to display and order numerical data.

As the data given is a numerical data, a stem-and-leaf plot would be appropriate.

5.
The table shows the sales of CD players in 3 different stores in a week. Which type of graph is appropriate to represent the data?
 Stores A B C Number of CD players sold 10 11 15 a. stem-and-leaf plot b. bar graph c. line graph d. circle graph

#### Solution:

A stem-and-leaf plot is an arrangement of digits that is used to display and order numerical data.

Circle graphs are the best type of graphs for showing the relative proportions of different categories to each other and to the whole.

A line graph shows the relationship between the dependent and independent variables when both are numerical and the dependent variable is a function of the independent variable.

A bar graph is appropriate for comparing different trials or different experimental groups.

The bar graph compares sales across stores.

Therefore, bar graph is the appropriate type of graph to represent the given data.

6.
In a class, 9 students like algebra, 11 like geometry, and 8 like statistics. Which type of graph can be used to show the data? a. stem-and-leaf plot b. bar graph c. line plot d. circle graph

#### Solution:

Circle graphs are the best type of graphs for showing the relative proportions of different categories to each other and to the whole.

A stem-and-leaf plot is an arrangement of digits that is used to display and order numerical data.

A bar graph is appropriate for comparing different trials or different experimental groups.

A line plot is usually used when there is one group of data.

So, the appropriate graph would be a line plot.

7.
The table shows the number of pizzas sold at Mary′s pizzeria last week.
 Toppings Onions Sausage Extra cheese Mushrooms Peppers Number of pizzas 8 11 3 5 2

Which of these graphs would be the most appropriate to represent the data? a. a stem-and-leaf-plot b. a line plot c. a line graph d. a double bar graph

#### Solution:

The data can be represented using a line plot by placing a 'x' for each pizza corresponding to that particular Topping.
[A line plot shows the frequency of data using a number line.]

A line plot would be more appropriate to represent the data.

8.
Chris recorded the sales of T-shirts from a cloth store. In the 1st week of January, he sold 280 T-shirts, in the 2nd week 290 T-shirts, in the 3rd week 276 T-shirts and in the 4th week 369 T-shirts. Which of the given graphs can we use to show the data? a. insufficient data b. stem-and-leaf plots c. line graphs d. line plots

#### Solution:

The data can be represented using a line graph to show the changes in the number of T-shirts sold in each week.
[A line graph is used to show the changes over time.]

A line graph can be used to show the data.

9.
The table shows the car sales in each month. Which graph can we use to show the data?  a. line plot b. stem-and-leaf plot c. bar graph d. circle graph

#### Solution:

A bar graph can be used to compare the number of cars sold in each month.
[A bar graph is used to compare data.]

So, a bar graph can be used to show the data.

10.
In a class of 32 students, 9 participated in Soccer, 8 in Volleyball, 5 in Table tennis and 10 in Basketball. Which of the given types of graph can we use to display the data? a. line plot b. stem-and-leaf plot c. circle graph d. bar graph

#### Solution:

A bar graph can be used to compare the number of students participating in each sport.
[A bar graph is used to compare data.]

So, a bar graph can be used to display the data.
