5.
Quantitative research uses hypotheses development as a starting point to then collect data and analyse it, towards checking the extent of accuracy of these hypotheses.
Show Answer
Correct Answer:
Correct answer is: (A) True.
Exam Relevance:
AP Statistics, GRE, GMAT, Research Methods in Psychology
Difficulty:
Easy
Concept notes:
Quantitative research involves formulating hypotheses and then collecting and analyzing data to test the accuracy of these hypotheses.
Common Mistakes:
A common misunderstanding is that quantitative research does not involve hypotheses, but rather only data collection and analysis without a specific starting point.
Explanations:
Quantitative research typically begins with the development of hypotheses. These hypotheses are then tested through the collection and analysis of data. The process aims to determine the extent to which the hypotheses are supported by the data. This structured approach ensures that the research is focused and systematic.
Option Analysis:
Option A:
This option correctly states that quantitative research uses hypotheses development as a starting point to collect and analyze data.
Option B:
This option incorrectly suggests that quantitative research does not use hypotheses development as a starting point.

A) Qualitative.
B) Quantitative.
C) Both.
D) Neither.
Show Answer
Correct Answer:
Correct answer is: (B) Quantitative.
Exam Relevance:
AP Statistics, GRE, GMAT, SAT
Difficulty:
Easy
Concept notes:
Quantitative data involves numerical measurements and can be counted or measured. Qualitative data involves descriptive, non-numerical information.
Common Mistakes:
A common misunderstanding is confusing quantitative data with qualitative data. Qualitative data would describe the pendulum's motion in words, not numbers.
