Understanding Data with Line Plots

The video tutorial teaches how to understand data from a story problem by using a line plot. Peter measures the heights of students in his class and records the data. The tutorial demonstrates how to create a line plot from this data, starting with the lowest measurement and adding dots for each student. It then shows how to analyze the plot to answer questions about the data, such as identifying the shortest and tallest groups and comparing the number of students taller or shorter than specific heights. The lesson concludes by highlighting the ease of answering questions using a line plot.

What is the main purpose of using a line plot in this lesson?

• To make the data look more colorful

• To confuse the students

• To better understand and analyze the data

• To replace the original data table

How many students are 48 inches tall according to Peter's data?

• Seven

• Eight

• Nine

• Six

Which group of students is the shortest in Peter's class?

• Students who are 60 inches tall

• Students who are 58 inches tall

• Students who are 52 inches tall

• Students who are 48 inches tall

Are there more students taller than 52 inches or shorter than 52 inches?

• The numbers are equal

• More students are shorter

• More students are taller

• There is no data available

How does the number of students taller than 55 inches compare to those shorter than 55 inches?

• More students are shorter

• More students are taller

• There is no data available

• The numbers are equal

Which group of students is the tallest in Peter's class?

• Students who are 58 inches tall

• Students who are 48 inches tall

• Students who are 60 inches tall

• Students who are 52 inches tall

What is the benefit of moving data from a table to a line plot?

• It makes the data harder to understand

• It changes the data values

• It allows for easier data analysis and question answering

• It removes unnecessary data
