measurement

is the integrative process of determining the
intensity (or amount) of information about constructs, concepts, or
objects.

scale measurement

involves assigning a set of scale descriptors to represent
the range of possible responses to a particular question.

categorical measurement

Use values that can be counted as parts of distinct
groups. The groups can be based on a characteristic or
label.

continuous measurement

Use values that can be expressed numerically and
placed in a logical order. Additionally, there is equal
distance between each data point.

nominal

The use of unique descriptors to identify each object
in a set.

ordinal

Establishes “relative magnitudes” between the
descriptors creating hierarchical rank-order relationships
among objects.

interval

Enables the researcher and respondent to identify,
understand, and express absolute (or assumed)
differences between objects.

ratio

A unique scale descriptor designated as being a “true
natural zero” or “true state of nothing.”.

mean

The average value within the distribution and is the
most- commonly used measure of central tendency.

median

The middle value of the distribution when ordered in
either ascending or descending sequence

mode

The value that appears in the distribution most often

range

Defines the spread of the data – the endpoints of the
distribution of values

standard deviation

The standard deviation describes the average
distance of the distribution values from the mean.

hypothesis

a claim about a population parameter

which is for nominal

mode

which is for ordinal

median

which is for interval

mean

which is for ratio
