qualitative graphs

Front

What is a qualitative graph?

Back

A qualitative graph is a type of graph that represents the relationship between variables without using numerical values, focusing instead on the general trends and behaviors of the data.

What does an increasing interval on a graph indicate?

Back

An increasing interval on a graph indicates that as the x-values increase, the y-values also increase.

Front

What does a decreasing interval on a graph indicate?

Back

A decreasing interval on a graph indicates that as the x-values increase, the y-values decrease.

Front

What is a constant interval on a graph?

Back

A constant interval on a graph is where the y-values remain the same as the x-values increase, indicating no change.

Front

How can you identify non-linear intervals on a graph?

Back

Non-linear intervals can be identified by observing sections of the graph that do not form a straight line, indicating a change in the rate of increase or decrease.

Front

What does it mean if a graph has multiple increasing intervals?

Back

Multiple increasing intervals mean that there are several sections of the graph where the y-values rise as the x-values increase.

Front

What is the significance of section labels (like A, B, C) in a qualitative graph?

Back

Section labels help to identify specific parts of the graph for analysis, making it easier to discuss changes in behavior or trends.

Front

How can you interpret a flat section on a qualitative graph?

Back

A flat section on a qualitative graph indicates that there is no change in the y-value as the x-value increases, suggesting a constant state.

Front

What does it indicate if a graph shows a steep slope?

Back

A steep slope on a graph indicates a rapid change in y-values with respect to x-values, suggesting a strong relationship between the variables.

Why is it important to analyze the intervals of a qualitative graph?

Back

Analyzing the intervals of a qualitative graph helps to understand the behavior of the data over different ranges, revealing trends and patterns.
