Tables and graphs > GraphsExercises
The table contains the number of fatal burn victims in the United States caused by fires between 1950 and 1982.
Draw a graph using the data from the first two columns. Explain which type of graph you have chosen and why.
Which variable is the dependent variable?
Can you reach a conclusion about the number of burn victims? Which helps you more, the table or the graph?
Why is the third column needed to be able to conclude that fire prevention measures started paying off after 1980?
Use the table to estimate the number of inhabitants of the United States in 1982.
Download and print the school doctor chart for girls, The expression P100 on this chart means that 100% of the girls is below this line.
Which two variables have been plotted against each other in the bottom half of this chart?
What is the meaning of the two preprinted graphs on this chart? Why are they there?
How can you use this chart to predict the height and the weight of a year old woman?
The table shows Marleen van Straaten's data. Her height has been measured every year on her birthday. draw her growth charts on the school physician's chart.
Is Marleen taller than average for her age? And what can you say about her weight?
When filling a glass vase from a steady flowing tap, you can see the water level in the vase rising. Below on the left are four vases of the same height, but of different forms. On the right there are four graphs representing the water level (in cm) charted against time (in seconds).

Why are all four curves so smooth?
Which graph belongs to which vase?
Draw the graphs of depending on when the water flows twice as fast.
The amount of carbondioxide (CO2) ande the amount of oxygen (O2) in the air are kept in balance because the plants on Earth transform carbondioxide into oxygen.
These graphs illustrate this.
Determine the length of the period for both graphs.
The amount of CO2 decreases from May through August. Explain why.
What is the minimum amount of CO2 in cm3 in the atmosphere in 1990? And what was the maximum found?
The maximum values in the upper graph correspond to the minimum values in the lower graph and vice versa. Give an explanation.
The graph shows a decreasing tendency for the ratio oxygen/nitrogen in the atmosphere. Draw a trend line depicting this.
Draw a trend line for the carbondioxide graph as well. Is there a correspondence between both lines?
Predict the amount of carbondioxide in January 2010 if this trend continues.
