Question

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?

Answer 1

This is a task for researcher which needs a lot of observation and patience. They have to organize all the data about the dosage, number of people and the time they are sleeping. This data cannot be done in a simple general template, it should be a random which would suit more for this analysis and we need a t-statistic for comparing details of both groups.

Answer 2

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

Further explanation

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
• Ordinal data
• Interval data (scale)
• Ratio data

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

Data analysis

• Non-statistical analysis
• Statistic analysis

Non-statistical analysis

• Qualitative data, i.e. non-audible data, non-statistical analysis is more appropriate to use
• Qualitative data is usually processed or analyzed based on its contents (substance).
• Non-statistical analysis is often also referred to as content analysis (content analysis), which includes descriptive, critical, comparative, and synthesis analysis.

Statistic analysis

• For quantitative data, i.e. data in the form of numbers or can be framed, statistical analysis is more appropriate to use
• Descriptive statistics and inferential statistics
• Descriptive research is not to test a hypothesis.
