Step: 1

Average test score = S u m o f a l l t h e t e s t s c o r e s N u m b e r o f s u b j e c t s

Step: 2

Sum of the test scores of the student = 82 + 95 + 73 + 97 + 70 + 93 = 510

Step: 3

Total number of subjects is 6.

Step: 4

So, Average test score = 510 6 = 85.

[Simplify.]

Correct Answer is : 85

Step: 1

Mean weight = S u m o f t h e w e i g h t s N u m b e r o f l i s t e d w e i g h t s

Step: 2

Sum of the weights = 9 + 31 + 14 + 11 + 49 + 34 + 15 + 5

Step: 3

= 168 lb

[Add the weights.]

Step: 4

Number of listed weights = 8

Step: 5

Mean weight = 168 8 = 21 lb

[Substitute and simplify.]

Step: 6

So, the mean weight of the data set is 21 lb.

Correct Answer is : 21 lb

Step: 1

Average score = total score number of games

[Formula for average.]

Step: 2

= 2 4 + 1 6 + 2 4 + 2 6 + 2 0 5

[Substitute the values.]

Step: 3

= 110 5

[Add the values in the numerator.]

Step: 4

= 22

[Divide.]

Step: 5

So, Ethan's average score was 22.

Correct Answer is : 22

Day | Exercise time (in minutes) |

Monday | 26 |

Tuesday | 18 |

Wednesday | 28 |

Thursday | 14 |

Friday | 11 |

Saturday | 23 |

Sunday | 41 |

Step: 1

Mean time = Sum of all times Number of days

Step: 2

= 26+28+14+18+23+11+41 7

[Substitute the values given in the table.]

Step: 3

= 161 7

[Add the values in the numerator.]

Step: 4

= 23

[Divide.]

Step: 5

So, Lauren spent a mean time of 23 minutes daily for exercise.

Correct Answer is : 23

Step: 1

The mode is the score that occurs most frequently.

Step: 2

104, 84, 88, 84, 100, 90 and 92

[Original scores.]

Step: 3

84, 84, 88, 90, 92, 100 and 104

[Arrange in order.]

Step: 4

84 occurred two times and no other score occurred more than one time.

Step: 5

So, the mode is 84.

Correct Answer is : 84

Step: 1

The middle number of an ordered data set is called the median of the data set.

Step: 2

2, 4, 8, 3, and 5

[Original data set.]

Step: 3

2, 3, 4, 5, and 8

[Arrange in ascending order.]

Step: 4

The middle number is 4.

Step: 5

So, the median is 4.

Correct Answer is : 4

Step: 1

The mean of set of data is the sum of all the data values divided by the number of data values.

Step: 2

The number of 'x' symbols over each name indicate the number of occurrences of the name in the data set.

Step: 3

Mean for the data cannot be calculated as we cannot mathematically add (Brown + Brown + Brown + Blue +Blue +Blue +Blue + Hazel + Hazel + Hazel +Hazel +Hazel + Hazel + Green +Green +Green ).

[Mean cannot be determined for categorical data.]

Step: 4

So, the mean for the data cannot be determined.

Correct Answer is : Cannot be determined

Step: 1

From the line plot, number of students who like Geometry, Algebra, Statistics and Probability are 5, 6, 4 and 1 respectively.

Step: 2

The mode is the data value that appears most often in a set of data.

Step: 3

The highest number of occurrences in the line plot is for Algebra.

Step: 4

So, the mode for the data shown in the line plot is Algebra.

Correct Answer is : Algebra

State | Number of TV Anchors |

California | 15 |

Los Angles | 12 |

New Jersey | 18 |

New York | 15 |

Texas | 18 |

Wyoming | 18 |

Step: 1

The total number of TV Anchors for the states = 15 + 12 + 18 + 15 + 18 + 18 = 96

Step: 2

Number of States (data values) = 6

Step: 3

Mean = Sum of the number of TV Anchors the number of states = 96 6 = 16

Step: 4

The mean number of TV Anchors in the states is 16.

Correct Answer is : 16

Step: 1

Median is the middle data value of a set of ordered data.

Step: 2

The ordered data set is 6, 6, 7, 7, 7, 7, 10, 10, 12, and 12.

Step: 3

As there are 10 data values in the set, the median of the data set is the average of the middle two numbers.

Step: 4

So, the median of the data set = 7 + 7 2 = 7.

Step: 5

So, the median age of the children is 7.

Correct Answer is : 7

Step: 1

Median is the middle data value of the ordered data set.

Step: 2

The ordered data set is 62, 63, 64, 66, 67, 68, 69, 69, 69, and 79.

Step: 3

As there are 10 data values in the set of data, the median of the data set is the average of the middle two numbers.

Step: 4

So, the median of the data set = 6 7 + 6 8 2 = 135 2 = 67.5.

Correct Answer is : 67.5

Step: 1

The middle number of an ordered data set is called the median of the data set.

Step: 2

5, 3, 8, 9, 17,12, 13, 33, 25, 31, and 21

[Original data set.]

Step: 3

3, 5, 8, 9, 12, 13, 17, 21, 25, 31, and 33

[Arrange the data set in ascending order.]

Step: 4

The median of the data set, the middle number, is 13.

Correct Answer is : 13

Step: 1

The number that occurs most frequently in a data set is called the mode.

Step: 2

46, 43, 29, 35, 20, 25, 14, 57, 46, 4, 57, 29, 46, and 5

[Original scores.]

Step: 3

4, 5, 14, 20, 25, 29, 29, 35, 43, 46, 46, 46, 57, and 57

[Arrange in ascending order.]

Step: 4

Since the number 46 appears the greatest number of times, the mode of the data set is 46.

Correct Answer is : 46

Step: 1

Mode is a number that occurs most often in a data set.

Step: 2

In the line plot shown, there are more crossmarks (**x**'s) above the number 12.

Step: 3

So the mode is $12.

[It means that the most number of apple baskets that Jessica has cost $12 each.]

Correct Answer is : 12
