Understanding Qualitative Graphs and Trends

The video tutorial explains qualitative graphs, which lack numerical data and rely on graph shapes to interpret scenarios. It uses a jogging example to illustrate five intervals: starting with a jog, taking breaks, slowing down, and returning home. The video emphasizes understanding graph intervals and the importance of line steepness in interpreting graph behavior.

What is a qualitative graph primarily used for?

• Calculating exact values

• Displaying numerical data

• Comparing statistical data

• Understanding the shape and trends

In the first interval, what activity is represented by the increasing line?

• Jogging

• Swimming

• Driving

• Cycling

What does a flat line in the second interval indicate?

• Constant distance

• Increasing speed

• Decreasing speed

• Variable distance

During the third interval, what change occurs in the movement?

• The speed increases

• The speed decreases

• The direction changes

• The distance remains constant

What does the fourth interval suggest about the activity?

• The person is running

• The person is taking a break

• The person is accelerating

• The person is lost

In the fifth interval, what does the steep line indicate?

• A change in direction

• A constant pace

• A fast return

• A slow return

What is the significance of the steepness of a line in a qualitative graph?

• It represents the graph's size

• It indicates the speed of change

• It determines the graph's shape

• It shows the color of the graph

What does a decreasing line in a qualitative graph typically represent?

• A decrease in distance

• An increase in distance

• An unknown change

• A constant distance

Why are numbers not necessary on a qualitative graph?

• Because they are always constant

• Because the focus is on trends and shapes

• Because they are too complex

• Because they are not visible

What should you pay attention to in a qualitative graph to understand the activity?

• The size of the graph

• The shape and steepness of the lines

• The labels on the axes

• The color of the graph
