Scientific Method & Data Analysis

A biology student wanted to study the effects of fertilizer on plants so they devised an experiment to test it. For plants in Group A, only water was given. For plants in Group B, both water and fertilizer was given.

Which would be a correct analysis of the data?

• Plants in Group A grew better than plants in Group B

• Plant growth flattened at around day 5

• Plants in Group B showed a decline in growth

• Plants in Group B showed in increase in growth

A biology student wanted to determine if there is a relationship between resting heart rate and body height. She gathered information from 12 classmates and constructed the graph shown.

Which of the following is true based on the data?

• As height increases, resting heart rate decreases

• As height increases, resting heart rate also increases

• As height decreases, resting heart rate increases

• Height and resting heart rate do not have a direction correlation

Fertilized eggs from the same species of sea turtle were incubated at different temperatures. The hatchling data is shown in the table.

Which of the following is supported by the data?

• The largest number of male sea turtles will develop at 28 C

• Female sea turtles develop at higher temperatures

• The sex of sea turtle offspring depends on the incubation temperature

• Most of the sea turtle eggs hatched if incubated at 26 C

A biology student wanted to determine if there is a relationship between resting heart rate and body height. She gathered information from 12 classmates and constructed the table shown.

Which of the following is best supported by the data in the table?

• The shorter the student, the higher the resting heart rate

• A higher resting heart rate results in student growth

• There is no direct correlation between height and resting heart rate

• The taller the student, the higher the resting heart rate

The graph shows the effect of temperature on population size of three different species of fish.

Which temperature range could support the growth of all three species?

• 40-45 C

• 0-5 C

• 30-35 C

• 15-20 C
