Numerical Data Used to Measure and Describe Characteristics of Groups

Numerical results from a test where the test is not a good measure of learning will not be helpful even if the numbers look impressive. Psychologist Stanley Smith Stevens developed the best-known classification with four levels or scales of measurement.

Data analysis is a process of inspecting cleansing transforming and modelling data with the goal of discovering useful information informing conclusions and supporting decision-making.

. This framework of distinguishing levels of measurement originated. The best data. Where Y i is the intervention effect estimated in the i th study W i is the weight given to the i th study and the summation is across all studies.

Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. The bigger the weight given to the i th study the more it will contribute to the weighted average see Section 103. Note that if all the weights are the same then the weighted average is equal to the mean intervention effect.

Data analysis has multiple facets and approaches encompassing diverse techniques under a variety of names and is used in different business science and social science domains. Nominal ordinal interval and ratio. Numerical evidence of impact is best.

Numerical evidence such as effect size can be very useful but data is only as good as its methods of collection analysis and the conclusions reached.
