Scatter Plots

What does a positive linear association in a scatter plot look like?

• As x-values increase, y-values also increase, forming a straight line.

• As x-values increase, y-values decrease, forming a straight line.

• There is no clear pattern between x-values and y-values.

• Y-values increase while x-values remain constant.

What type of association does a nonlinear scatter plot represent?

• A relationship where the data points do not form a straight line.

• A relationship where the data points form a perfect straight line.

• A relationship that shows no correlation between variables.

• A relationship that is linear but with some outliers.

What is the y-axis in a scatter plot?

• The horizontal axis that typically represents the independent variable.

• The vertical axis that typically represents the dependent variable.

• The axis that shows the correlation between two variables.

• The axis that is used for labeling the data points.

How can you identify an outlier in a scatter plot?

• An outlier appears as a point that is significantly distant from the other points.

• An outlier is always the highest point in the scatter plot.

• An outlier is a point that lies on the trend line.

• An outlier is a point that is repeated multiple times.

What is the purpose of a scatter plot?

• To visually represent the relationship between two quantitative variables.

• To display the frequency of categorical data.

• To show the distribution of a single variable.

• To compare the means of different groups.

What does it mean if the points on a scatter plot show that as x-values increase, y-values increase?

• It indicates a positive correlation between the two variables.

• It indicates a negative correlation between the two variables.

• It indicates no correlation between the two variables.

• It indicates a random relationship between the two variables.

What does a negative association in a scatter plot indicate?

• As x-values increase, y-values decrease.

• As x-values increase, y-values increase.

• There is no relationship between x-values and y-values.

• As x-values decrease, y-values remain constant.

What is a nonlinear association?

• A relationship where the data points do not follow a straight line pattern.

• A relationship that can be represented by a straight line.

• A relationship where all data points are identical.

• A relationship that shows a constant rate of change.

What is the x-axis in a scatter plot?

• The vertical axis that typically represents the dependent variable.

• The horizontal axis that typically represents the independent variable.

• The axis that represents the correlation between two variables.

• The axis that is used for labeling the data points.

What is a scatter plot?

• A type of bar graph that displays data in rectangular bars.

• A graph that shows the relationship of two data sets.

• A circular chart divided into sectors that represent proportions.

• A line graph that depicts changes over time.
