## Example Questions

### Example Question #251 : Statistics

Refer to the above line graph, which tracks the high temperature in a town over one calendar week.

Of the days shown, between which two consecutive days did the peak temperature decrease the most?

**Possible Answers:**

Between Monday and Tuesday

Between Wednesday and Thursday

Between Tuesday and Wednesday

Between Friday and Saturday

**Correct answer:**

Between Monday and Tuesday

The segments that represent decreases are the ones that go from upper left to lower right. There are four, and the steepest is the one between Monday and Tuesday. This is the correct response.

### Example Question #1 : Line Graphs

Refer to the above line graph, which tracks the high temperature in a town over one calendar week.

Of the days shown, how many had a peak temperature at or above ?

**Possible Answers:**

**Correct answer:**

The dot representing Thursday is the only one of the seven that appears below 60 on the graph, so 6 is the correct response.

### Example Question #252 : Statistics

Refer to the above line graph, which tracks the high temperature in a town over one calendar week.

How many days shown have a peak temperature higher than Friday's high temperature?

**Possible Answers:**

**Correct answer:**

Only the three dots representing the peak temperatures of Sunday, Monday, and Tuesday are higher than the one representing that of Thursday, so the correct response is three.

### Example Question #253 : Statistics

Use the following line graph to answer the question:

How many enrollments were there in January?

**Possible Answers:**

**Correct answer:**

Let's look at the line graph.

We can see the bottom axis displays the individual months. We can see the scale on the left displaying the number of enrollments.

So, to find the number of enrollments in January, we will first locate January on the bottom axis. We can see that it is the first one listed.

Now, we will see which number it corresponds with. We can see that it lines up with 10.

Therefore, the number of enrollments in January is 10.

### Example Question #254 : Statistics

Use the following line graph to answer the question:

Approximately, how many 12th grade enrollments were there in 2013?

**Possible Answers:**

**Correct answer:**

Let's look at the graph:

If we look at the year 2013, we can see the data point is between 120 and 140.

We can also see that it is much closer to 140 than it is to 120.

From looking at the location of the data point, we can approximate that there were 136 12th grade enrollments in 2013.

### Example Question #2 : Line Graphs

The following graph charts the amount of rain received per month over the span of a year.

What is the average amount of rain, in inches, received in the first six months of the year?

**Possible Answers:**

**Correct answer:**

Start by finding the values for the first six months of the year.

In January, there was inches.

In February and March, there were inches per month.

In April, there was inches.

In May, there was inches.

In June, there was inches.

Recall how to find the average for a set of numbers:

Plug in the values for the rainfall and divide by the number of values.

### Example Question #255 : Statistics

The following graph charts the amount of rain received per month over the span of a year.

By what percent did the amount of rainfall increase between March and April?

**Possible Answers:**

**Correct answer:**

Recall how to find the percent change for two values:

The new value in this case would be the value from April, and the old value would be the value from March.

Plug in the correct values to find the percent change:

### Example Question #2101 : Ged Math

The following graph charts the amount of rain received per month over the span of a year.

What is the median amount of rainfall in the last six months of the year?

**Possible Answers:**

**Correct answer:**

Start by finding the values from the last six months of the year.

July | 2.25 |

August | 1.75 |

September | 1.5 |

October | 3.5 |

November | 3.75 |

December | 2 |

Next, place these values in increasing order:

Since there is an even number of values, the median will be the number between the third and fourth terms. In this case, the median will be between and .

The value in between those numbers is .

### Example Question #256 : Statistics

The following graph charts the number of attendees at a theme park over the course of a year.

By what percentage did attendance at the park increase from April to May?

**Possible Answers:**

**Correct answer:**

Recall how to find the percent change:

In this case, the new value is the number of attendees in May, and the old value is the number of attendees in April.

From the graph, you can see that there were in May and in April.

Plug these numbers into the equation to find the percent change.

### Example Question #2 : Line Graphs

The following graph charts the number of attendees at a theme park over the course of a year.

The increase in the number of attendees between April and May is how much larger than the increase in the number of attendees between June and July?

**Possible Answers:**

**Correct answer:**

Start by looking at the graph and finding out how many attendees there were for the listed months.

There were attendees in April, in May, in June, and in July.

Now, the increase in attendees between April and May is , and the increase in attendees from June to July is .

Thus, the difference in the amount of increases is .
