Interpreting Line Plots with Whole Numbers

In this video, Mr. J explains how to interpret a line plot by analyzing survey data on the number of pets students have. The video covers counting the total number of students surveyed, identifying students with at least three pets, counting those with one or two pets, and calculating the total number of pets. The tutorial emphasizes understanding how each 'X' on the line plot represents a student and how to derive meaningful insights from the data. The video concludes with a summary of the key points discussed.

What is the primary data represented in the line plot?

• Number of sports played by students

• Number of students in each grade

• Number of pets students have

• Number of books students read

How is each surveyed student represented in the line plot?

• By a bar

• By a number

• By a dot

• By an X

What does having no X's above a number signify?

• All students have that number of pets

• Data is missing

• No data available

• No students have that number of pets

How many students were surveyed in total?

• 16

• 18

• 17

• 15

How many students have at least three pets?

• 7

• 6

• 5

• 4

How many students have exactly one or two pets?

• 10

• 7

• 8

• 9

What is the total number of pets owned by the students?

• 33

• 34

• 32

• 35

How many pets do the students with four pets contribute to the total?

• 16

• 14

• 12

• 10

What value does each X represent in the context of the total number of pets?

• The number of students without pets

• The number of pets each student wishes to have

• The number of pets each student actually has

• The number of students surveyed

Why are some numbers on the line plot not associated with any X's?

• Because those numbers are reserved for future surveys

• Because the data for those numbers was lost

• Because no students have that exact number of pets

• Because those numbers represent unavailable data
