Graphing Scales and Increments

The video tutorial explains how to create a bar graph, focusing on determining appropriate scale increments. It covers the components of a bar graph, 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 using a bar graph?

• To calculate mathematical equations

• To display data in a circular format

• To list items in a sequence

• To visually represent collected information

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

• A pie chart

• A title

• A scale

• Vertical and horizontal lines

What is a common misconception about scale increments?

• They should always be less than 10

• They can only count in increments of one

• They can count in increments of any number

• They must always be even numbers

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

• Increments of 2

• Increments of 1

• Increments of 10

• Increments of 5

Why is it not ideal to use increments of 1 for Mrs. Davidson's cupcake order?

• It would result in too many numbers on the scale

• It would make the graph too colorful

• It would not include all types of cupcakes

• It would make the graph too simple

What is the ideal range of numbers for a clear scale on a graph?

• 13 to 20 numbers

• 21 to 30 numbers

• 5 to 12 numbers

• 1 to 4 numbers

Which increment allows for clear representation of 40 chocolate cupcakes and 60 vanilla cupcakes?

• Increments of 10

• Increments of 5

• Increments of 2

• Increments of 1

Why is 25 easy to represent on a graph with increments of 10?

• Because 25 is a multiple of 10

• Because 25 is between 20 and 30

• Because 25 is less than 30

• Because 25 is a prime number

What is the best increment to use for Mrs. Davidson's cupcake data?

• Increments of 10

• Increments of 1

• Increments of 2

• Increments of 5

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

• It reduces the number of bars

• It simplifies the data

• It makes the graph colorful

• It allows for easy counting of 40 and 60
