Scatter Plot Relationships and Interpretations

The video tutorial explains scatter plots, which are graphs showing relationships between two data sets. It covers three examples: height vs. weight, dog feeding frequency vs. food left, and age vs. favorite number. The first example shows a positive relationship, the second a negative one, and the third no relationship. The tutorial highlights how to interpret scatter plots and identify trends or lack thereof.

What is the primary purpose of a scatter plot?

• To display a single data point

• To show a relationship between two data sets

• To list data in a table format

• To calculate averages

In a scatter plot, what does a positive relationship indicate?

• The variables are unrelated

• As one variable increases, the other also increases

• There is no change in the variables

• As one variable increases, the other decreases

What is the trend shown in the height vs. weight scatter plot?

• Cyclic relationship

• Positive relationship

• No relationship

• Negative relationship

What is the significance of a squiggly line in a scatter plot?

• It indicates a positive trend

• It marks the origin

• It highlights the highest point

• It shows a break in the data

In the dog feeding scatter plot, what happens as the number of feedings increases?

• The amount of food left fluctuates randomly

• The amount of food left remains constant

• The amount of food left decreases

• The amount of food left increases

What type of relationship is shown in the dog feeding vs. food left scatter plot?

• Positive relationship

• No relationship

• Cyclic relationship

• Negative relationship

What does a negative relationship in a scatter plot indicate?

• The variables are unrelated

• Both variables remain constant

• As one variable increases, the other decreases

• As one variable increases, the other increases

In the age vs. favorite number scatter plot, what is observed?

• A positive relationship

• A negative relationship

• A cyclic relationship

• No relationship

What does it mean when a scatter plot shows no relationship?

• The points are randomly scattered

• The points form a perfect circle

• The points form a straight line

• The points are clustered in one area

Which of the following is an example of a data set with no correlation?

• Height vs. Weight

• Temperature vs. Ice Cream Sales

• Dog Feeding vs. Food Left

• Age vs. Favorite Number
