Question 5

Which of the following is an example of a question that CANNOT be addressed by science?

Accepted Answer

Question 6

A regression line in a scatterplot is best described as:

Accepted Answer

A line that predicts the value of the dependent variable for any given value of the independent variable, represented by an equation.

Question 7

When would you use a scatter plot instead of a bar graph?

Accepted Answer

When both the independent and dependent variables are numerical.

Question 8

Which of the following best defines a hypothesis?

Accepted Answer

A statement based on observations that can be tested through experiments.

Question 9

In the mouse predation experiment, what was the control group?

Accepted Answer

The models representing mice in their natural habitat.

Question 10

Which of the following best describes quantitative data?

Accepted Answer

Data that is collected through the use of statistics and can be measured numerically.

Question 11

A student is analyzing a graph where the independent variable is on the x-axis and the dependent variable is on the y-axis. Which of the following is the correct way to represent this relationship?

Accepted Answer

Place the independent variable on the x-axis and the dependent variable on the y-axis.

Question 12

Which of the following is a key similarity between science and inquiry?

Accepted Answer

Both use questioning and investigation to understand concepts.

Quantitative data.

Question 14

Which of the following is an example of qualitative data?

Accepted Answer

Question 15

In the context of scientific experiments, what is the purpose of a control group?

Accepted Answer

To provide a baseline for comparison to determine the effect of the independent variable.

Question 16

A student claims that science is always a straightforward process. Which of the following best refutes this claim?

Accepted Answer

Science is a process that involves challenge, reasoning, and creativity, and is not strictly linear.

Question 17

Which of the following best describes the relationship between a hypothesis and an experiment?

Accepted Answer

A hypothesis is tested by conducting experiments to collect data that supports or refutes it.

Question 18

Accepted Answer

The growth of the plants.

Question 19

Which of the following is a reason why some questions cannot be addressed by science?

Accepted Answer
