is perhaps the most widely used statistics software package within human behavior research. It offers the ability to easily compile descriptive statistics, parametric and non-parametric analyses, as well as graphical depictions of results through the graphical user interface (GUI).

SPSS (Statistical Package for the Social Sciences)

is a free statistical software package that is widely used across both human behavior research and in other fields. While R is a very powerful software, it also has a steep learning curve, requiring a certain degree of coding

is an analytical platform and programming language that is widely used by engineers and scientists. As with R, the learning path is steep, and you will be required to create your own code at some point.

MatLab

is a statistical analysis platform that offers options to use either the GUI, or to create scripts for more advanced analyses. It is a premium solution that is widely used in business, healthcare, and human behavior research alike.

SAS

is premium software primarily used within statistics related to biology, but offers a range of capabilities that can be used across various fields.

GraphPad Prism

software that offers a range of both basic and fairly advanced statistical tools for data analysis.

Minitab

offers a wide variety of tools for data visualization and simple statistics. It is simple to generate summary metrics and customizable graphics and figures, making it a usable tool for many who want to see the basics of their data.

Excel

The researcher has direct contact with the interviewee. The researcher gathers information by asking questions to the interviewee

Direct personal interviews

These methods of data collection involve sourcing and accessing existing data that were originally collected for the purpose of the study

Indirect/Questionnaire Method

It is a group interview of approximately six to twelve people who share similar characteristics or common interests. A facilitator guides the group based on a predetermined set of topics.

Focus Group

It is a method of collecting data where there is direct human intervention on the conditions that may affect the values of the variable of interest.

Experiment

It is a method of collecting data on the phenomenon of interest by recording the observations made about the phenomenon as it actually happens. involves collecting information without asking questions.

Observation

It may include availability of resources, man power, budget, ethics and sampling frame.

Non-statistical considerations

It will include the desired precision of the estimate.

Statistical considerations

Also called sampling error, the level of precision, is the range in which the true value of the population is estimated to be.

Level of Precision

− It is statistical measure of the number of times out of 100 that results can be expected to be within a specified range. For example, a confidence interval of 90% means that results of an action will probably meet expectations 90% of the time.

Confidence Interval

Depending upon the target population and attributes under consideration, the degree of variability varies considerably. The more heterogeneous a population is, the larger the sample size is required to get an optimum level of precision

Degree of Variability

An object on which a measurement is taken. This is the basic unit of observation, sometimes called an element. In studying human populations, observation units are often individuals

Observation unit

The complete collection of observations we want to study.

Target population

The collection of all possible observation units that might have been chosen in a sample; the population from which the sample was taken.

Sampled population

A subset of a population

Sample

A unit that can be selected for a sample. We may want to study individuals, but do not have a list of all individuals in the target population. Instead, households serve as the sampling units, and the observation units are the individuals living in the households

Sampling unit

A list, map, or other specification of sampling units in the population from which a sample may be selected. For a survey using in-person interviews, the sampling frame might be a list of all street addresses.

Sampling frame

It is a plan you set forth to be sure that the sample you use in your research study represents the population from which you drew your sample.

Sampling technique/Sampling Strategies

This involves problems in your sampling, which reveals that your sample is not representative of your population.

Sampling Bias
