Year 11 General Mathematics Revision - Bivariate Data

Bivariate Data involves how many variables?

• Zero

• One

• Two

• Three

Univariate Data involves how many variables?

• Zero

• One

• Two

• Three

What type of graph do we use most often to represent Bivariate data?

• Histogram

• Pie Chat

• Sctatterplot

• Box Plot

The measure of a linear association between two variables is called:

• Causation

• Correlation

• Outlier

• Can be called all of the above.

The equation we use to model a line of best fit is:

• y = a - bx

• y = b + ax

• y = a + bx

• y = ax - b

In the equation y = a + bx the letter a represents:

• slope

• x intercept

• y intercept

• origin

In the equation y = a + bx, the letter b represents:

• slope

• x intercept

• y intercept

• origin

To describe the strength of an association we use:

• Positive/Negative

• Linear/Non-Linear

• Weak/Moderate/Strong

• Outliers

To describe the direction of an association we use:

• Positive/Negative

• Linear/Non-Linear

• Weak/Moderate/Strong

• Outliers

To describe the form of an association we use:

• Positive/Negative

• Linear/Non-Linear

• Weak/Moderate/Strong

• Outliers
