Understanding Line Plots

The video tutorial introduces line plots and guides students through a star drawing activity to collect data. It explains how to determine the maximum, minimum, range, median, mode, and outliers from the collected data. The tutorial emphasizes understanding these statistical concepts through practical examples.

What was the unique challenge students faced while drawing stars?

• Drawing stars with a specific pattern

• Drawing only the outline of stars

• Drawing stars with a specific size

• Drawing stars with a specific color

What is the maximum number of stars drawn by a student?

• 10 stars

• 16 stars

• 26 stars

• 20 stars

How do you calculate the range of the data set?

• Add the maximum and minimum values

• Divide the maximum value by the minimum value

• Subtract the minimum value from the maximum value

• Multiply the maximum and minimum values

What is the median in a data set?

• The difference between the highest and lowest numbers

• The most frequently occurring number

• The average of all numbers

• The middle number when arranged in order

If two numbers are left in the middle when finding the median, what should you do?

• Ignore them

• Choose the smaller number

• Choose the larger number

• Add them and divide by two

What is the mode of the data set?

• The average of all numbers

• The number that appears most frequently

• The highest number in the data set

• The lowest number in the data set

Which number was the mode in the star-drawing activity?

• 16

• 26

• 12

• 10

What is an outlier in a data set?

• A number that is repeated the most

• The largest number in the data set

• The smallest number in the data set

• A number that is far from the rest

Why might a number be considered an outlier?

• It is the sum of all numbers

• It is the average of the data set

• It is the result of a mistake or unique condition

• It is the most common number

What should be done with an outlier in a data set?

• Ignore it

• Include it in the data

• Double its value

• Exclude it from the data
