Understanding Line Plots

This video tutorial covers the concept of line plots, comparing them to bar graphs, and explaining how to create and interpret them. It includes practical examples using bug lengths and exercises to reinforce learning. The tutorial also addresses common questions and mistakes in reading line plots, and provides advanced problems for further practice.

What is a line plot primarily used for?

• To show the frequency of data along a number line using X's

• To display data using bars

• To compare two different data sets

• To calculate averages

In the bug length example, how many bugs were a quarter inch long?

• One

• Four

• Three

• Two

What is an outlier in a data set?

• A data point that is the smallest in the set

• A data point that is separated from the rest of the data

• A data point that is the largest in the set

• A data point that is the average of the set

How do you find the difference between the largest and smallest data points in a line plot?

• Subtract the smallest data point from the largest

• Divide the largest data point by the smallest

• Multiply the largest and smallest data points

• Add the largest and smallest data points

What is the first step in creating a line plot from a data set?

• Draw the number line

• Order the data from least to greatest

• Count the data points

• Label the axes

How many customers did the food critic collect data from in the example?

• Six

• Five

• Seven

• Eight

What is the median in a data set?

• The average of all data points

• The most frequently occurring data point

• The middle value when data is ordered

• The sum of all data points

In the ribbon length example, what is the difference between the longest and shortest ribbons?

• 6/6 yard

• 5/6 yard

• 4/6 yard

• 1/6 yard

How do you convert an improper fraction to a mixed number?

• Subtract the denominator from the numerator

• Multiply the numerator by the denominator

• Add the numerator and the denominator

• Divide the numerator by the denominator

What is the total distance run by students in Mr. Boren's class?

• 3 and 3/5 miles

• 4 and 2/5 miles
