Front

What is Conditional Relative Frequency?

Back

The probability of an event occurring given that another event has already occurred, often expressed as a fraction of the total outcomes.

Front

Define Negative Correlation.

Back

A relationship between two variables in which one variable increases as the other decreases.

Front

What is a Two-Way Table?

Back

A table that displays the frequency distribution of two categorical variables, allowing for the comparison of their relationships.

Front

What is Marginal Frequency?

Back

The total counts of a single category in a two-way table, found by summing the frequencies across one variable.

Front

How do you calculate Conditional Relative Frequency?

Back

Divide the frequency of the joint occurrence of two events by the total frequency of the condition.

Front

What does it mean if there is No Correlation between two variables?

Back

Changes in one variable do not predict changes in the other variable; there is no discernible relationship.

Front

What is a Scatter Plot?

Back

A graphical representation of two variables, showing the relationship between them using dots for each data point.

Front

Explain Positive Correlation.

Back

A relationship between two variables where both variables increase or decrease together.

Front

What is the significance of the slope in a scatter plot?

Back

The slope indicates the direction and strength of the relationship between the two variables.

Front

What does it mean if a relationship cannot be determined from a scatter plot?

Back

It indicates that the data points do not show a clear trend or pattern, making it difficult to infer a relationship.
