Scatter Plots

Benjamin and Jackson are conducting a science experiment. They want to understand the relationship between the time spent studying and the marks obtained. Which graph should they use to display this relationship?

• A table that shows numerical data

• A scatter plot, which is a graph that displays the relationship between two variables

• A type of pie chart

• A graph that displays the relationship between three variables

Ethan, Avery, and Anika are working on a data analysis project for their statistics class. They are trying to understand how scatter plots can be used in their analysis. Can you help them understand?

• Scatter plots are used to display categorical data in their project.

• Scatter plots are used to show the distribution of a single variable in their project.

• Scatter plots are used to compare two unrelated variables in their project.

• Scatter plots are used to visualize the relationship between two variables in their project.

Zoe and Arjun are working on a science project where they are plotting a scatter plot. What are the two variables they would represent on their scatter plot?

• Red and Blue

• X and Y

• Two variables they are studying

• A and B

Samuel, Emma, and Aria are conducting a science experiment where they are observing the relationship between the temperature and the number of chirps made by crickets. They plot their observations on a scatter plot. How should they interpret the relationship between these variables on the scatter plot?

• By determining the color of the plotted points.

• By observing the pattern or trend formed by the plotted points.

• By measuring the distance between the plotted points.

• By calculating the average of the plotted points.

Grace, Lily, and Aria are studying the relationship between the number of hours they study and their grades. What does a positive correlation on their scatter plot indicate?

• As the number of hours they study increases, their grades also tend to increase.

• As the number of hours they study increases, their grades tend to decrease.

• There is no relationship between the number of hours they study and their grades.

• As the number of hours they study decreases, their grades tend to increase.

Avery, Zoe, and Kai are studying the relationship between the number of hours they study and their grades. They notice a negative correlation on their scatter plot. What does this indicate?

• The number of hours they study and their grades are not related to each other.

• As the number of hours they study increases, their grades also increase.

• As the number of hours they study increases, their grades decrease.

• There is no relationship between the number of hours they study and their grades.

Lily, James, and Zoe are studying the relationship between the number of hours they study and their grades. If their scatter plot shows no correlation, what does this indicate?

• There is a weak positive correlation between their study hours and grades

• There is a perfect positive correlation between their study hours and grades

• There is a perfect negative correlation between their study hours and grades

• There is no relationship or association between their study hours and grades

In a science project, Lily, Harper, and Noah collected data and plotted a scatter plot. How can outliers in their data affect the interpretation of their scatter plot?

• Outliers can distort the overall pattern or trend in their data and lead to inaccurate conclusions.

• Outliers can improve the accuracy of the conclusions drawn from their scatter plot.

• Outliers only affect the x-axis values in their scatter plot.

• Outliers have no effect on the interpretation of their scatter plot.

Hannah, Lily, and Sophia are working on a science project where they are plotting the number of hours they study against their test scores. Why would they add a trend line to their scatter plot?

• To make the scatter plot look more visually appealing

• To add more data points to the scatter plot

• To show the exact relationship between the number of hours they study and their test scores

• To show the general pattern or direction of the relationship between the number of hours they study and their test scores.

Jackson, Kai, and Benjamin are conducting a science experiment. They are collecting data and plotting it on a scatter plot. How can they determine the strength of the relationship between the variables they are studying?

• They can determine the strength by looking at the color of the points on the scatter plot.

• They can use a ruler to measure the distance between the points on the scatter plot.

• They can visually analyze the scatter plot and look for patterns or trends. They can also calculate the correlation coefficient.

• They can count the number of points on the scatter plot.
