To determine whether a new sleeping pill has an effect that varies with dosage, a researcher randomly assigns adult insomniacs, in equal numbers, to receive either 4 or 8 grams of the sleeping pill. the amount of sleeping time is measured for each subject during an 8-hour period after the administration of the dosage. what type of design is this, and what type of statistic is needed to analyze the data?

The above research uses quantitative research and uses interval data in analyzing data

The research design determines statistical techniques, not vice versa statistical techniques determine the research design. Statistics are used to serve and as a tool in research, not to master it.

Based on the measurement level of the research variables that are quantified:

Nominal data

The data is determined based on the process of classification or categorization.

Ordinal data

Data that has a sequence or may be sorted by rank or certain attributes.

Interval data (scale)

Data that can be grouped based on the same size (units/units); can be sorted by the group as ordinal data.

Ratio data

Data in quantification has an absolute zero (0); meaning 'zero quantity' (0) can be entered as a data member. Ratio data
