Understanding Scale Increments and Graphs

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 different increments affect the readability of the graph.

What is the main purpose of this lesson?

• To determine scale increments for a bar graph

• To learn how to bake cupcakes

• To calculate the area of a rectangle

• To understand how to draw a pie chart

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

• A scale

• A title

• Vertical and horizontal lines

• A pie chart

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

If a scale counts in increments of 5, how many numbers would be on the scale for a range of 0 to 20?

• 4

• 5

• 6

• 7

Why might increments of 2 be a better choice than increments of 5 for a certain data set?

• Because it is a more common increment

• Because it is easier to count by twos

• Because it allows for clearer representation of smaller numbers

• Because it uses fewer numbers on the scale

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

• 21 to 30

• 13 to 20

• 5 to 12

• 1 to 4

Why is a scale increment of 10 suitable for Mrs. Davidson's cupcake order?

• It is the most common increment

• It is the smallest possible increment

• It clearly represents all the data points

• It allows for fewer numbers on the scale

Which number is not clearly represented when counting by tens?

• 30

• 20

• 25

• 40

What is the benefit of using benchmark numbers for scale increments?

• They are easier to remember

• They make the graph look more colorful

• They help in clear representation of data

• They reduce the number of bars needed

How many numbers would be on a scale counting by tens up to 60?

• 8

• 5

• 6

• 7
