MAP Applied Methods and Techniques 4 — Questions and Answers
Question 1: A student's results do not support the hypothesis. What is the best next step?
- Change the data to match the hypothesis
- Report the results honestly and revise the hypothesis (Correct answer)
- Ignore the experiment
- Delete the trials that disagree
Correct answer: Report the results honestly and revise the hypothesis
Scientists report actual results and use them to revise or form new hypotheses.
Question 2: Which SI unit is used to measure mass?
- Liter
- Newton
- Kilogram (Correct answer)
- Meter
Correct answer: Kilogram
The kilogram is the SI base unit of mass.
Question 3: On a graph, the independent variable is usually placed on which axis?
- The y-axis
- The x-axis (Correct answer)
- Either axis randomly
- Neither axis
Correct answer: The x-axis
By convention, the independent variable goes on the horizontal x-axis.
Question 4: A survey asks only students in the chess club about favorite school activities. What is the main problem with this sample?
- It is too large
- It is biased and not representative (Correct answer)
- It uses too many questions
- It is random
Correct answer: It is biased and not representative
Sampling only one group skews results and does not represent all students.
Question 5: Which strategy works best for checking the answer to 156 ÷ 12 = 13?
- Add 156 and 12
- Multiply 13 × 12 (Correct answer)
- Subtract 13 from 156
- Divide 12 by 13
Correct answer: Multiply 13 × 12
Multiplication is the inverse of division, so 13 × 12 should equal 156.
Question 6: When taking notes from a research source, why should a student record the source information?
- To make the notes longer
- To cite the source and avoid plagiarism (Correct answer)
- To memorize the author's name
- To skip paraphrasing
Correct answer: To cite the source and avoid plagiarism
Recording source details allows proper citation and prevents plagiarism.
Question 7: A scatter plot shows that as hours studied increase, test scores also increase. This shows a:
- Negative correlation
- Positive correlation (Correct answer)
- No correlation
- Proof that studying causes higher scores
Correct answer: Positive correlation
Both variables increase together, which is a positive correlation; correlation alone does not prove cause.
