Investigation 1 and 2 Review [Variables and Patterns]

Front

What is a variable in an experiment?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types. In an experiment, variables are what you measure and manipulate.

Front

What is a constant rate?

Back

A constant rate means that a quantity increases or decreases by the same amount over equal intervals of time.

Front

What does a graph represent in data analysis?

Back

A graph visually represents data, showing relationships between variables, trends, and patterns.

Front

What is the meaning of 'coordinate' in a graph?

Back

A coordinate is a set of values that show an exact position on a graph, typically represented as (x, y).

Front

How do you identify the greatest increase in a data set?

Back

To identify the greatest increase, compare the differences between values in the data set and find the largest difference.

Front

What does a time-distance graph show?

Back

A time-distance graph shows how distance changes over time, illustrating the speed and movement of an object.

Front

What is a steady rate of movement?

Back

A steady rate of movement means traveling at a consistent speed without speeding up or slowing down.

Front

How do you read a graph?

Back

To read a graph, identify the axes, understand the scale, and analyze the plotted points or lines to interpret the data.

Front

What is the significance of the slope in a graph?

Back

The slope of a graph indicates the rate of change; a steeper slope means a greater rate of change.

Front

What does it mean when a graph levels off?

Back

When a graph levels off, it indicates that the variable is no longer increasing or decreasing significantly, suggesting a stable state.
