❶Although a distinction is commonly drawn between qualitative and quantitative aspects of scientific investigation, it has been argued that the two go hand in hand.

Project Analysis: Find Answers Using the Quantitative Method
Analyze Quantitative Data

After all, girls may not like giraffes as much as boys or boys may want to skip the panda, etc. Qualitative research always comes first, so in our scenario to determine the problems with low sales of the Pillow Pet qualitative research shows the reason for the low sales.

For example, perhaps a focus group of children were gathered with a variety of designs to determine favorites and the not so favorites. Once qualitative researched showed no child wanted the polar bear or snake pillow pet, each were specifically questioned on why to determine the exact reasons. Once these reasons are discovered, quantitative research can begin. In keeping with our Pillow Pet example, from the focus group, perhaps the following was found:.

No child of either gender liked the way the snake pillow felt when unfolded and found it uncomfortable. Females thought the snake looked mean. The polar bear was not white and black in color. From here, the quantitative research method can begin by using various methods to determine why faults occurred and ways to fix them. Qualitative research shows what is wrong, where quantitative methods reveal ways to improve products based on end-user input; or numerical data that can be analyzed.

When using quantitative research, a project manager can go about this process a few different ways. Hybrid Sampling — For the uncomfortable Pillow Pet design, a new design offered a bigger pillow-head area, the pillow snake was given a happier smile and the Panda Pillow Pet was offered in recognizable black and white colors.

The focus group needed to answer specific questions about what they liked about the new Pillow Pets including questions such as, do you think the snake pillow is comfortable and why? Does the snake look happy or scary? What if we made the Panda red and yellow? Here, through learned responses, the new design, if developed using the quantitative method will help to increase sales. The answers provide quantitative numbers to increase sales based on pooling a group.

Parent Surveys — Telephone or online surveys are developed to be answered by parents of the original focus group of children. Through these surveys, parents are asked what specifically they think their child would rather see in the snake or the panda.

Again, survey data analysis reveals if indeed a redesign would work or fail. The production cost of the scary snake is dropped and the designers can focus on what children like best based on parental input.

However, following are examples of research questions where quantitative methods may be appropriately applied: The collection of numerical data through quantitative research methods lends itself well to large variety of research questions. The following modules in this series will explore when to choose quantitative methods, how to write a good research question, types of quantitative methods, data analysis, ethics and many other topics that will lead to better understanding of quantitative research.

The data collected is numeric, allowing for collection of data from a large sample size. Statistical analysis allows for greater objectivity when reviewing results and therefore, results are independent of the researcher. Numerical results can be displayed in graphs, charts, tables and other formats that allow for better interpretation.

Data analysis is less time-consuming and can often be done using statistical software. Results can be generalized if the data are based on random samples and the sample size was sufficient. Data collection methods can be relatively quick, depending on the type of data being collected.

In quantitative data analysis you are expected to turn raw numbers into meaningful data through the application of rational and critical thinking. Quantitative data analysis may include the calculation of frequencies of variables and differences between variables. A quantitative approach is usually.
