Bivariate quantitative data refers to:

• Data that involves two categorical variables.

• Data that involves two variables, one of which is categorical and the other quantitative.

• Data that involves two quantitative variables.

• Data that involves one quantitative variable and one qualitative variable.

A scatter plot is used to:

• Show the distribution of a single variable.

• Display the relationship between two variables by plotting individual data points.

• Represent the frequency of data in different categories.

• Compare the averages of different groups.

A deterministic interpretation of a relationship suggests that:

• The relationship is unpredictable and variable.

• The outcome of one variable is completely determined by the other variable with no randomness.

• The outcome is based on probability and chance.

• The relationship involves multiple factors with no clear pattern.

In the context of a line, the slope represents:

• The point where the line intersects the x-axis.

• The change in the dependent variable relative to the change in the independent variable.

• The point where the line intersects the y-axis.

• The constant value of the dependent variable.

Informal inferences are:

• Conclusions drawn from formal statistical tests and experiments.

• Predictions made based on random sampling.

• Generalizations or conclusions made based on observed data without formal testing.

• Conclusions drawn only through controlled laboratory experiments.

A statistical investigative question is one that:

• Can be answered with a simple yes or no.

• Can be answered by performing a mathematical calculation.

• Requires data collection and analysis to answer.

• Is only concerned with a single data point.

The line of best fit in a scatter plot:

• Passes through all the data points.

• Shows only the outliers in the data.

• Connects the highest and lowest data points.

• Passes through the middle of the scattered data points.

An unbiased statistical study is one where:

• The data collection process ensures all segments of the population are fairly represented.

• The researcher selects data points that support their hypothesis.

• The study is conducted without any form of random sampling.

• The results are interpreted in a way that favors one outcome over another.

The x-intercept of a graph is the point where:

• The x-intercept of a graph is the point where:

• The graph crosses the x-axis.

• The slope of the graph is zero.

• The graph has a positive slope.

The predicted slope (rate of change) of a linear relationship represents:

• The value of the dependent variable when the independent variable is zero.

• The rate at which the graph reaches its maximum value.

• The distance between the highest and lowest data points.

• The amount the dependent variable changes for each unit increase in the independent variable.
