MATH 110 - Module 1
1. Data Things about which information can be collected and analyzed.
2. Data set An arranged collection of information that contains the various categories of
data collected for a specific study.
3. Element The individual and unique entry in a data set about which data has been
collected, analyzed, and presented in the same manner.
4. Variable A particular, measurable attribute that the researcher believes is needed to
describe the element in their study.
5. Observation All the information collected for each element in a study.
6. Qualitative Descriptive
7. Quantitative Numerical
8. Nominal level of Names, labels, qualities
measurement
9. Ordinal level of mea- Qualitative or quantitative. Can be arranged in order, or ranked.
surement
10. Interval level of Only quantitative data. Ordered, and meaningful differences between data
measurement entries can be calculated.
11. Ratio level of mea- Quantitative, ordered, meaningful differences can be calculated. A zero entry
surement is an inherent zero (none).
12. Cross-sectional data Where a researcher collects info or measurements for each variable on an
element at the same point.
13. Time series data Data collected over a specific period of time.
