Question

Classify the following data. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, continuous, 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: ____________.

Answer 1

IQ scores are quantitative continuous data measured at the interval scale level, representing intellectual ability through numbers with meaningful differences but no true zero point.

Step-by-step explanation:

The IQ scores of students at the local college are quantitative data because they consist of numbers that represent different levels of intellectual ability. This data can be considered continuous because IQ scores, although often reported as whole numbers, can be expressed as fractions and are the result of measurement. The level of measurement for IQ scores would be at the interval scale level because there is a definite ordering with meaningful differences between values but no true zero point (an IQ of 0 does not mean the absence of intelligence).

Answer 2

1. Quantitative.
2. Discrete.
3. Interval Scale.

Step-by-step explanation:

1. 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.
2. 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.
3. 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.
