Choosing Scale Increments for Graphs

The video tutorial explains how to create bar graphs, focusing on determining appropriate scale increments. It covers the components of bar graphs, common misconceptions about scale increments, and how to choose the right scale for clarity. The tutorial uses examples, such as Mrs. Davidson's cupcake orders, to illustrate how to apply scale increments to data effectively.

What is the main purpose of this lesson?

• To learn about different types of graphs

• To determine scale increments for a bar graph

• To understand how to draw a bar graph

• To learn how to bake cupcakes

Which of the following is NOT a component of a bar graph?

• Title

• Bars

• Scale

• Legend

What is a common misconception about scale increments?

• They can only count in increments of one

• They can count in any increment

• They must always be even numbers

• They should always be less than 10

Which increment would be best for a scale if you have 8 daisies and 22 tulips?

• 2

• 5

• 1

• 10

Why is an increment of 5 not suitable for representing 8 daisies?

• Because 5 is not a benchmark number

• Because 8 is not visible on the scale

• Because 5 is too large

• Because 8 is not a multiple of 5

How many numbers would be on the scale if it counted in increments of 1 for Mrs. Davidson's cupcakes?

• 61

• 25

• 60

• 40

What is the ideal range of numbers on a scale for easy readability?

• 20 to 30

• 10 to 20

• 5 to 12

• 1 to 5

Which increment was determined to be the best for Mrs. Davidson's cupcake data?

• 10

• 5

• 2

• 1

Why is 25 easy to represent on a scale counting by tens?

• Because it is less than 30

• Because it is a benchmark number

• Because it is between 20 and 30

• Because it is a multiple of 10

What is the benefit of using increments of 10 for the cupcake data?

• It is easier to count by tens

• It allows for fewer numbers on the scale

• It makes the graph colorful

• It makes the graph more complex
