What is Statistical Inference? Statistical inference is the process of using a sample to infer the properties of a population. Statistical procedures use sample data to estimate the characteristics of the whole population from which the sample was drawn. Scientists typically want to learn about a population.
Sep 4, 2020 · Inferential statistics have two main uses: making estimates about populations (for example, the mean SAT score of all 11th graders in the US). testing hypotheses to draw conclusions about populations (for example, the relationship between SAT scores and family income).
- Descriptive statistics summarize the characteristics of a data set. Inferential statistics allow you to test a hypothesis or assess whether your da...

Mar 25, 2024 · Inferential statistics is a branch of statistics that uses sample data to make generalizations, predictions, or inferences about a larger population. Unlike descriptive statistics, which summarize data, inferential statistics go beyond the data at hand to estimate parameters, test hypotheses, and predict future trends.
Jul 29, 2024 · Inference is the process of drawing conclusions about a population based on data from a sample. In statistics, this involves estimating population parameters (like means or proportions) and testing hypotheses to determine if observed data supports a certain claim or theory.
Inferential statistics is very useful and cost-effective as it can make inferences about the population without collecting the complete data. Some inferential statistics examples are given below: Suppose the mean marks of 100 students in a particular country are known.
Statistical inference is the process of analysing the result and making conclusions from data subject to random variation. It is also called inferential statistics. Hypothesis testing and confidence intervals are the applications of the statistical inference. Statistical inference is a method of making decisions about the parameters of a ...

Now that we’ve defined inferential statistics and explained how it differs from descriptive statistics, let’s take a look at some of the most common tests within the inferential realm. It’s worth highlighting upfront that there are many different types of inferential tests and this is most certainly not a comprehensive list – just an introductory list to get you started.
