A student set up an experiment to test the effect of the number of seedlings planted in one pot on the rate of growth. All conditions in the experiment were the same, except for the number of plants in each pot. The results are shown in the graph below.
The dependent variable was
the number of plants per plot
time in days
average plant growth
the amount of water per pot
A student set up an experiment to test the effect of the number of seedlings planted in one pot on the rate of growth. All conditions in the experiment were the same, except for the number of plants in each pot. The results are shown in the graph below.
According to the graph, which statement is true concerning the growth of the plants?
The plants in the pot with only 5 plants grew to be an average of 40 cm tall in 30 days
The plants in the pot with only 10 plants grew to be an average of 30 cm tall in 20 days.
The plants in the pot with 15 plants grew an average of 20 cm taller after a period of 10 days.
The plants in the pot with 20 plants grew an average of 20 cm taller after a period of 40 days.
A student wanted to investigate the effect of light on the rate of ripening of tomatoes. She set up four pots of the same size with identical amounts of soil, water, and type of tomato plants. Each plant was exposed to a different intensity of light as shown in the table below.
The independent variable in this experiment is the
type of tomato plant
amount of soil provided
color of tomatoes
light intensity
To report the final results, which label would be most appropriate for the third column of the data table?
Height of Tomato Plants (cm)
Average Ripening Time (days)
Average Weight of Tomatoes per Plant (grams)
Acidity of Tomatoes (pH)
The bar graph below shows the height of a plant at the end of each week of a five-week growth period. Which statement represents a valid conclusion based on the information in the graph?
The plant was given water during the first three weeks, only.
The plant will grow faster during the sixth week than it did during the fifth week.
The plant grew fastest during the first three weeks, and then it grew slower.
The plant grew slowest during the first three weeks, and then it grew faster.
When should a bar graph be used?
When comparing two things
When both variables include quantitative data
When one variable is qualitative and the other is quantitative
The graph below shows atmospheric carbon dioxide levels since the year 1880.Which of the following conclusions can be drawn from this graph
Atmospheric carbon dioxide levels are responsible for global temperature change.
Atmospheric carbon dioxide levels have been rising at about the same rate for the past century.
Atmospheric carbon dioxide levels have remained the same over the past century.
Atmospheric carbon dioxide levels have been rising at an increasingly higher rate as the past century has progressed.
