Qualitative Descriptions for Graphs

Front

What is a qualitative description in the context of graphs?

Back

A qualitative description refers to the characteristics of a graph that explain how a variable changes over time without using numerical values, focusing on trends such as increasing, decreasing, or constant rates.

Front

What does it mean when a graph shows 'increasing at a constant rate'?

Back

It means that the value of the variable is rising steadily over time, with equal increments in each time interval.

Front

What does 'increasing at a varying rate' indicate on a graph?

Back

It indicates that the value of the variable is rising, but the increments are not equal; the rate of increase changes over time.

Front

How can you describe a section of a graph that is 'decreasing at a constant rate'?

Back

This means that the value of the variable is falling steadily over time, with equal decrements in each time interval.

Front

What does 'decreasing at a varying rate' mean in a graph?

Back

It means that the value of the variable is falling, but the decrements are not equal; the rate of decrease changes over time.

Front

What is the significance of a section labeled 'E' in a graph?

Back

Section 'E' typically represents a specific part of the graph where a particular trend or behavior of the variable is observed, such as varying rates of change.

Front

How can you determine if a puppy's weight increased faster at the start or end of a period from a graph?

Back

By analyzing the slope of the graph: a steeper slope indicates a faster rate of increase, while a flatter slope indicates a slower rate.

Front

What does it mean if a graph is described as having a 'constant rate of change'?

Back

It means that the variable changes by the same amount in each time interval, resulting in a straight line when graphed.

Front

What is the difference between 'constant rate' and 'varying rate' in graph descriptions?

Back

A constant rate means the change is uniform over time, while a varying rate means the change is inconsistent and can speed up or slow down.

Front

What does it mean when a graph shows a 'short time' at a certain point?

Back

It indicates that the variable remained relatively stable or unchanged for a brief period before continuing to change.
