Classify the following data. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, co
ntinuous, or neither, and indicate the level of measurement for the data. The IQ scores of students at the local college. Qualitative or quantitative: ____________. Discrete, continuous, or neither: _____________. Level of measurement: ____________.
The IQ scores are measured numerically. This makes it quantitative data. Quantitative data provide numerical measures which can be used to perform arithmetric operations such as addition, subtraction, multiplication and division. Results from these kind of data can be used to provide meaningful and explanatory results to certain phenomena.
IQ scores are discrete because they are always expressed as integers. that is in whole numbers and not in fractions e.g 100, 120, 60.
The level of measurement is on an interval scale because the difference between values have meanings. Larger values mean higher IQ. for example, the difference in IQ numbers between two people for represents something real.
