Study Notes

Types of Data

Countable Data: Involves individual values, such as counting coin tosses until obtaining tails or counting births in a specific area until a male is born.
Continuous Data: Results in infinitely many possible quantitative values that cannot be counted individually. Example includes measurements like lengths from 0 cm to 12 cm.

Categorical Data

Categorical (Qualitative) Data: Comprises names or labels rather than numerical counts or measurements.

Levels of Measurement

Nominal Level: Data consists solely of names, labels, or categories with no inherent order (e.g. survey responses of yes, no, undecided).
Ordinal Level: Data can be ordered, but the differences between values cannot be accurately determined or are meaningless (e.g. course grades).
Interval Level: Data can be arranged in order, and the differences between data values are meaningful; however, it lacks a true zero point (e.g. body temperature).
Ratio Level: Data can be organized in order, differences are meaningful, and it possesses a true zero point indicating the absence of a quantity (e.g. class time).
