What is a scatterplot?
A scatterplot is a type of data visualization that displays the relationship between two categorical variables.
A scatterplot is a type of data visualization that displays the relationship between two numerical variables.
A scatterplot is a type of data visualization that displays the relationship between a numerical variable and a categorical variable.
A scatterplot is a type of data visualization that displays the relationship between two numerical variables using a line graph.
How are scatterplots used to represent data?
Scatterplots are used to visually represent the relationship between two variables by plotting individual data points on a graph.
Scatterplots are used to compare data across different time periods.
Scatterplots are used to show the distribution of a single variable.
Scatterplots are used to display categorical data.
What are the two variables represented on a scatterplot?
independent variable and dependent variable
input variable and output variable
x-axis and y-axis
control variable and experimental variable
How can you determine the relationship between two variables using a scatterplot?
By analyzing the x-axis values only.
By calculating the mean of the variables.
By examining the pattern of points on the scatterplot.
By drawing a line of best fit through the points.
What does a positive correlation on a scatterplot indicate?
As one variable increases, the other variable tends to decrease.
There is no relationship between the two variables.
As one variable decreases, the other variable tends to increase.
As one variable increases, the other variable also tends to increase.
What does a negative correlation on a scatterplot indicate?
As one variable decreases, the other variable decreases.
As one variable increases, the other variable increases.
There is no relationship between the two variables.
As one variable increases, the other variable decreases.
What does no correlation on a scatterplot indicate?
A positive relationship between the variables.
A negative relationship between the variables.
A strong relationship between the variables.
No relationship between the variables
How can outliers affect the interpretation of a scatterplot?
Outliers have no effect on the interpretation of a scatterplot.
Outliers can improve the accuracy of estimates and summary statistics.
Outliers only affect the visual appearance of the scatterplot, not the interpretation.
Outliers can distort the overall pattern and trend in the data, leading to inaccurate estimates and summary statistics.
What is the purpose of adding a trendline to a scatterplot?
To visually represent the relationship between variables and identify patterns or trends.
To confuse the viewer and make the data harder to interpret.
To make the scatterplot look more visually appealing.
To add unnecessary complexity to the scatterplot.
How can you use a scatterplot to make predictions?
By analyzing the pattern or trend observed on the scatterplot.
By connecting the dots on the scatterplot with a straight line.
By ignoring the scatterplot and using other data sources.
By randomly selecting points on the scatterplot.
