What is a scatterplot?
A scatterplot displays values of two variables as points on a coordinate grid.
True or false: Scatterplots show relationships.
True, because they illustrate correlations between two variables.
Difference between positive and negative correlation?
Positive correlation: both variables increase together. Negative correlation: one increases while the other decreases.
Fill in the blank: A scatterplot shows __________.
The relationship between two quantitative variables.
What does a cluster of points indicate?
It indicates a strong relationship or pattern between the two variables.
What is the purpose of a trend line?
A trend line summarizes the direction of data points and helps identify correlation.
True or false: Outliers affect trend lines.
True, because outliers can skew the results and misrepresent the trend.
How is correlation measured?
Correlation is measured using a correlation coefficient, ranging from -1 to 1.
Scenario: A scatterplot shows time vs. distance. What does a flat line mean?
It indicates no movement or constant distance with respect to time.
What does a correlation coefficient of 0 imply?
It implies no correlation between the two variables being analyzed.
True or false: Scatterplots can be used for categorical data.
False, because scatterplots require quantitative data for both axes.
What does a steep slope in a scatterplot indicate?
A steep slope suggests a strong relationship between the variables, either positive or negative.
What is an outlier?
An outlier is a data point that significantly deviates from the other data points.
Scenario: A scatterplot shows age vs. income. What might a downward trend indicate?
It might indicate that income decreases as age increases, or it could show a different relationship.
What is the x-axis typically used for?
The x-axis often represents the independent variable in a scatterplot.
What about the y-axis?
The y-axis typically represents the dependent variable in a scatterplot.
Fill in the blank: A scatterplot with a random pattern indicates __________.
No correlation between the two variables.
True or false: Scatterplots can show multiple sets of data.
True, by using different colors or shapes for different data sets.
How can scatterplots help in decision making?
They visually represent relationships between variables, aiding in trends identification.
