What is bivariate data?

Back

Bivariate data involves two variables that can be analyzed to determine relationships or correlations between them.

What is a scatterplot?

Back

A scatterplot is a graph that displays values for two variables for a set of data, showing how one variable is affected by another.

Front

What does a positive correlation indicate in a scatterplot?

Back

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

Front

What does a negative correlation indicate in a scatterplot?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatterplot, used to predict values.

Front

How do you interpret the slope of a line of best fit?

Back

The slope indicates the rate of change of the dependent variable (y) for each unit change in the independent variable (x).

Front

What is an outlier in a dataset?

Back

An outlier is a data point that differs significantly from other observations, potentially indicating variability or error.

Front

What is the purpose of a frequency table?

Back

A frequency table organizes data to show how often each value occurs, helping to summarize and analyze the data.

Front

How can you determine the number of players who are counselors from a frequency table?

Back

By locating the row or column that specifies 'counselors' and counting the corresponding frequency.

Front

What does it mean if a scatterplot shows no correlation?

Back

No correlation means there is no discernible relationship between the two variables; changes in one do not affect the other.
