Descriptive Statistics
Descriptive statistics is the term given to the analysis of data that helps describe, show or summarize data (i.e. the sample) in a meaningful way such that, for example, patterns might emerge from the data. Descriptive statistics do not, however, allow us to make conclusions beyond the data we have analysed or reach conclusions regarding any hypotheses we might have made. They are simply a way to describe our data.
The Distribution  The Central Tendency 



The Dispersion  


Inferential Statistics
Inferential statistics allow the researcher to generalize their findings from the sample data to the larger population. They help assess the strength of the relationship between the independent (causal) variables, and the dependent (effect) variables. With inferential statistics, we are trying to reach conclusions that extend beyond the immediate data alone (i.e. our sample). For instance, we use inferential statistics to try to infer from the sample data what the population might think.
