Accepted Answer

Hello, everyone. Let's take a look at this question together. A research study categorizes participants by their favorite season, spring, summer, fall, or winter. Are these data qualitative or quantitative, and what is the level of measurement? So, in order to solve this question, we have to recall what we have learned about what qualitative data is, and what quantitative data is, as well as the different levels of measurement to determine whether the favorite seasons of the Research study participants is qualitative data or quantitative data and what level of measurement these seasons represent. And we can recall that qualitative data describes categories or qualities. Whereas quantitative data involves numerical values that represent a measurable quantity, and considering that the study categorizes participants by their favorite season, which is a category, we know that this data. It is qualitative because the participants are grouped by their favorite season, of which their favorite season is a category and not a numerical value, so it is not quantitative data and instead is qualitative data. And now we have to determine what is the level of measurement for the different seasons, which we know that there are 4 levels of measurement in statistics, starting with the nominal level of measurement, which involves categories with no inherent order, such as hair color or gender. Then we have the ordinal level of measurement, which involves categories with a meaningful order but unequal or unmeasurable intervals between them, such as letter grades or satisfaction ratings. Then we have the interval level of measurement, which involves numerical values with equal spacing, but No true zero, such as temperature in Celsius. And lastly, we have the ratio level of measurement, which involves numerical values with equal spacing and a true zero, allowing for meaningful ratios such as height, weight, or age. And again, considering that the research study categorized. participants by their favorite seasons, we can identify that seasons refers to a category that has no inherent order, therefore, the level of measurement is nominal, as the categories which are spring, summer, fall, and winter, have no inherent order or ranking. So we know that the data is qualitative and the level of measurement is nominal, which makes answer choice D the correct answer, and all other answer choices are incorrect. I hope you found this video to be helpful. Thank you and goodbye.
