What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables where each point represents an observation in the dataset, showing the relationship between the variables.

Front

What does a linear relationship in a scatterplot indicate?

Back

A linear relationship indicates that as one variable increases or decreases, the other variable tends to increase or decrease in a consistent manner.

Front

What does a non-linear relationship in a scatterplot indicate?

Back

A non-linear relationship indicates that the relationship between the variables does not follow a straight line, and may involve curves or other patterns.

Front

How can you determine if a scatterplot shows no relationship?

Back

A scatterplot shows no relationship when the points are scattered randomly without any discernible pattern or trend.

Front

What is the purpose of using scatterplots in data analysis?

Back

Scatterplots are used to visually assess the relationship between two quantitative variables, helping to identify trends, correlations, and potential outliers.

Front

What does the correlation coefficient indicate in a scatterplot?

Back

The correlation coefficient quantifies the strength and direction of the relationship between two variables, ranging from -1 (perfect negative correlation) to +1 (perfect positive correlation).

Front

What is the significance of outliers in a scatterplot?

Back

Outliers are data points that fall far from the trend of the rest of the data, and they can significantly affect the interpretation of the relationship between the variables.

Front

How can you interpret the slope of a line of best fit in a scatterplot?

Back

The slope of the line of best fit indicates the rate of change of the dependent variable for each unit change in the independent variable.

Front

What is the difference between dependent and independent variables in a scatterplot?

Back

The independent variable is plotted on the x-axis and is manipulated or controlled, while the dependent variable is plotted on the y-axis and is measured or observed.

Front

What does it mean if a scatterplot has a positive correlation?

Back

A positive correlation means that as one variable increases, the other variable also tends to increase.
