What is inferential statistics in psychology?
a broad class of statistical techniques that allow inferences about characteristics of a population to be drawn from a sample of data from that population while controlling (at least partially) the extent to which errors of inference may be made. Compare descriptive statistics. …
How descriptive and inferential statistics are used in psychology?
Descriptive statistics are used to summarize the data and inferential statistics are used to generalize the results from the sample to the population. In turn, inferential statistics are used to make conclusions about whether or not a theory has been supported, refuted, or requires modification.
How is inferential statistics used in research?
Inferential statistics use measurements from the sample of subjects in the experiment to compare the treatment groups and make generalizations about the larger population of subjects. There are many types of inferential statistics and each is appropriate for a specific research design and sample characteristics.
What are the types of inferential statistics?
The most common methodologies in inferential statistics are hypothesis tests, confidence intervals, and regression analysis. Interestingly, these inferential methods can produce similar summary values as descriptive statistics, such as the mean and standard deviation.
What are the 4 types of inferential statistics?
The following types of inferential statistics are extensively used and relatively easy to interpret: One sample test of difference/One sample hypothesis test. Confidence Interval. Contingency Tables and Chi Square Statistic.
What is the purpose of inferential statistics?
The goal of inferential statistics is to discover some property or general pattern about a large group by studying a smaller group of people in the hopes that the results will generalize to the larger group.
What are the four types of descriptive statistics?

Is inferential statistics qualitative or quantitative?
By making inferences about quantitative data from a sample, estimates or projections for the total population can be produced. Quantitative data can be used to inform broader understandings of a population, or to consider how that population may change or progress into the future.
What are the difference between descriptive and inferential statistics?
Descriptive statistics summarize the characteristics of a data set. Inferential statistics allow you to test a hypothesis or assess whether your data is generalizable to the broader population.
