A class counted the number of pets owned by four groups. Table: Group A has 5 pets, Group B has 7 pets, Group C has 3 pets, and Group D has 5 pets. Find the mean number of pets.
Mean means add the values and divide by how many values there are.
The mean is 5 pets. Add 5 + 7 + 3 + 5 = 20, then divide by 4 groups to get 5. - 2
Five students recorded how many books they read in a month. Table: Ana read 2, Ben read 4, Cara read 4, Diego read 6, and Eli read 9. Find the mode.
The mode is 4 books because 4 appears more often than any other number. - 3
A garden club measured plant heights in centimeters. Table: Plant 1 is 12 cm, Plant 2 is 15 cm, Plant 3 is 15 cm, Plant 4 is 18 cm, and Plant 5 is 20 cm. Find the median height.
Median means the middle number after the values are in order.
The median height is 15 centimeters. The values are already in order, and the middle value is 15. - 4
A soccer team recorded goals scored in six games. Table: Game 1 has 0 goals, Game 2 has 2 goals, Game 3 has 1 goal, Game 4 has 3 goals, Game 5 has 4 goals, and Game 6 has 2 goals. Find the mean number of goals.
The mean is 2 goals. Add 0 + 2 + 1 + 3 + 4 + 2 = 12, then divide by 6 games to get 2. - 5
A weather table shows high temperatures for five days. Table: Monday 70 degrees, Tuesday 72 degrees, Wednesday 68 degrees, Thursday 75 degrees, and Friday 70 degrees. Find the mode temperature.
Look for the number that repeats the most.
The mode temperature is 70 degrees because 70 appears twice and the other temperatures appear once. - 6
A math quiz table shows these scores: 80, 90, 85, 100, and 95. Find the mean score.
The mean score is 90. Add 80 + 90 + 85 + 100 + 95 = 450, then divide by 5 scores to get 90. - 7
A farm stand kept a table of apples sold in four hours. Table: Hour 1 sold 8 apples, Hour 2 sold 12 apples, Hour 3 sold 10 apples, and Hour 4 sold 14 apples. Find the median number of apples sold.
When there are two middle numbers, add them and divide by 2.
The median is 11 apples. Put the numbers in order as 8, 10, 12, 14. The middle is between 10 and 12, so the median is 11. - 8
A classroom table shows the number of pencils at six tables: 6, 6, 4, 8, 6, and 10. Find the mode.
The mode is 6 pencils because 6 appears three times, more than any other number. - 9
Five classes collected recycling. Table: Class A collected 15 pounds, Class B collected 20 pounds, Class C collected 25 pounds, Class D collected 30 pounds, and Class E collected 10 pounds. Find the mean pounds collected.
Add all the pounds first, then divide by the number of classes.
The mean is 20 pounds. Add 15 + 20 + 25 + 30 + 10 = 100, then divide by 5 classes to get 20. - 10
A player wrote down game scores in a table: 3, 7, 7, 5, 9, 5, and 7. Find the mode score.
The mode score is 7 because 7 appears three times, more often than any other score. - 11
A smoothie stand recorded cups sold by flavor. Table: Strawberry 9, Banana 6, Mango 9, Peach 4, and Berry 7. Find the median number of cups sold.
Order the cup amounts from least to greatest before finding the middle.
The median is 7 cups. In order, the numbers are 4, 6, 7, 9, 9, and the middle value is 7. - 12
A sticker table shows how many students had each number of stickers. Table: 1 sticker was held by 2 students, 2 stickers by 3 students, 3 stickers by 4 students, and 4 stickers by 1 student. Find the mode number of stickers.
The mode is 3 stickers because 3 stickers was the amount held by the most students, with 4 students. - 13
A frequency table shows quiz point totals. Table: 1 point was earned by 2 students, 2 points by 3 students, 3 points by 4 students, and 4 points by 1 student. Find the mean point total.
Use the frequency table to write or imagine the full list of scores before finding the mean.
The mean is 2.5 points. The total points are 1 + 1 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 4 = 25, and there are 10 students, so 25 divided by 10 is 2.5. - 14
A test score table shows this frequency information: score 80 happened 2 times, score 90 happened 3 times, and score 100 happened 1 time. Find the median score.
A frequency tells how many times a value appears.
The median score is 90. The ordered list is 80, 80, 90, 90, 90, 100, and the two middle values are both 90. - 15
The cafeteria recorded milk cartons sold each day. Table: Monday 20, Tuesday 25, Wednesday 25, Thursday 30, and Friday 35. Find the mean, median, and mode.
The mean is 27 cartons because 20 + 25 + 25 + 30 + 35 = 135 and 135 divided by 5 is 27. The median is 25 cartons because it is the middle value. The mode is 25 cartons because it repeats.
