Each requires different collection and analysis methods, so its important to understand the difference between the two. These are data that can be counted, but not measured. Scientific objectivity: Quantitative data can be interpreted with statistical analysis, and since statistics are based on the principles of mathematics, the quantitative approach is viewed as scientifically objective and rational (Carr, 1994; Denscombe, 2010). All data that are the result of counting are called quantitative discrete data. Had enough theory and want some action? The variable is continuous because it is not countable. Can take on any value in a number line, and have no clear space between them. What defines them as discrete is that there is a clear and consistent leap between variables and that these gaps dont take into account the difference. A(n) _________ is a person or object that is a member of the population being studied. Is it nominal or interval? January 14. (1994).

Generally, you can use the following criteria to determine whether to go with qualitative data, quantitative data, or a mixed methods approach to collecting data for your project. The main differences between quantitative and qualitative data lie in what they tell us, how they are collected, and how they are analyzed. Carr, L. T. (1994). Using a t-test to compare the mean ratings of the two groups, you find a significant difference and support for your hypothesis. Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings. The algebraic and logical operations still apply (+,-,*,/,%,|,&). To illustrate this, lets once again consider the dataset from the previous example: For the quantiative variable Seasons Played, we can calculate the following metrics: These metrics give us a good idea of where the center value is located as well as how spread out the values are for this variable. Qualitative Research in Psychology, 3, 77101. For this reason, discrete data are, by their nature, relatively imprecise. TheStreet Ratings evaluates over 25,000 mutual funds, stocks and ETFs using a range of fundamental analysis, technical analysis and economic data.

Measuring angles in radians might result in such numbers as , and so on. B. C. Whats the difference between quantitative and qualitative methods? The variable is quantitative because it is a numerical measure. Labels and categories used in surveys and questionnaires, e.g. Both research types require raw data; Both are used to measure results; Sometimes one type of research complements the other.
