Quantitative data can help you see the big picture
Validating your hypotheses: Quantitative research will get you numbers that you can apply statistical analysis to in order to validate your hypotheses. Was that problem real or just someone’s perception? The hard facts obtained will enable you to make decisions based on objective observations.
Finding general answers: Quantitative research has more respondents than qualitative research because it is easier to conduct a multiple-choice survey than a series of interviews or focus groups. Therefore it can help you definitely answer broad questions like: Do people prefer you to your competitors? Which of your company’s services are most important? What ad is most appealing?
