The ability to gather large volumes of accurate and timely data is a strength of quantitative research. Researchers are able to gain a deeper understanding of patterns, trends and relationships by using numerical analyses. Quantitative analyses are also generally more objective, as they can be measured precisely and repeated. This helps to ensure that the internal validity of the study. These types of studies tend to be easier to duplicate, as they use standardized data which can easily be compared across trials.
It is difficult to translate findings between populations or settings. In addition, certain factors (such emotions) may not be measurable numerically and make it more difficult to cover certain research topics. It can also be hard for the reader to fully understand results when they are only reported as numbers or percentages.
