To collect valid data for statistical analysis, you first need to specify your hypothesesand plan out your research design.
In most cases, it’s too difficult or expensive to collect data from every member of the populationyou’re interested in studying. Instead, you’ll collect data from a sample. Statistical analysis allows you to apply your findings beyond your own sample as long as you use appropriate sampling procedures. You should aim for a sample that is representat...
Once you’ve collected all of your data, you can inspect them and calculate descriptive statisticsthat summarize them.
A number that describes a sample is called a statistic, while a number describing a population is called a parameter. Using inferential statistics, you can make conclusions about population parameters based on sample statistics. Researchers often use two main methods (simultaneously) to make inferences in statistics. 1. Estimation:calculating popul...
