What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What does the vertical line test determine?

Back

The vertical line test determines if a graph represents a function. If any vertical line crosses the graph more than once, it is not a function.

Front

In an experiment, what is the dependent variable?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by the independent variable.

What is the purpose of a control group in an experiment?

Back

A control group is used as a standard for comparison to determine the effect of the independent variable.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between two or more variables.

What is the formula for the slope of a line?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.
