Which of the following factors must be taken into account quantitative research?
A. Measurement
B. Causality
C. Replication
D. Exclusion of statistical analysis
E. Less importance to standardization
Choose the most appropriate answer from the questions given below:

Correct option is A

Quantitative research is a systematic, empirical investigation of quantitative properties and phenomena and their relationships. It uses numerical data to quantify and analyze problems, and it typically involves a deductive approach.
All of the following factors must be taken into account in quantitative research:
 Measurement: Quantitative research must use reliable and valid measurement instruments to collect data.
 Causality: Quantitative research should be designed to establish causal relationships between variables.
 Replication: Quantitative research studies should be able to be replicated by other researchers to verify the findings.
