Different statistical tests and when to use them
The five basic methods are mean, standard deviation, regression, hypothesis testing, and sample size determination.
It is widely used by governments, businesses, banking entities, insurance companies, etc..
How do you know which statistic to use?
Three criteria are decisive for the selection of the statistical test, which are as follows:
1the number of variables,2types of data/level of measurement (continuous, binary, categorical) and.3the type of study design (paired or unpaired)..How do you use statistical analysis?
.
- Step 1: Write your hypotheses and plan your research design
- Step 2: Collect data from a sample
- Step 3: Summarize your data with descriptive statistics
- Step 4: Test hypotheses or make estimates with inferential statistics
- Step 5: Interpret your results
Statistical tools in research
A statistical test provides a mechanism for making quantitative decisions about a process or processes.
The intent is to determine whether there is enough evidence to "reject" a conjecture or hypothesis about the process.
The conjecture is called the null hypothesis..
Statistical tools in research
They're used to conduct research, evaluate outcomes, develop critical thinking, and make informed decisions.
Statistics can be used to inquire about almost any field of study to investigate why things happen, when they occur, and whether reoccurrence is predictable..
When should statistical analysis be used?
Statistical analysis can be used in situations like gathering research interpretations, statistical modeling or designing surveys and studies.
It can also be useful for business intelligence organizations that have to work with large data volumes..

When should you use a statistical test?
Statistical tests are used in hypothesis testing.
They can be used to: determine whether a predictor variable has a statistically significant relationship with an outcome variable. estimate the difference between two or more groups..
Where is statistical analysis used?
Statistical Analysis Defined
It's the science of collecting, exploring and presenting large amounts of data to discover underlying patterns and trends.
Statistics are applied every day – in research, industry and government – to become more scientific about decisions that need to be made..
