## Descriptive statistics and inferential statistics

###
Descriptive statistics are statistics such as central tendency and dispersion

Inferential statistics is when you infer results from a smaller sample such as study showing the taller people are smarter for that sample so it can be inferred this is true for all people (it isn’t)

In order to make an inference about the target population you have to see if our results are significant,

Inferential statistics can show the probability of that a set if data has happened by chance or due to the IV. The accosted level of something occurring by chance is less then 5% or else the hypothesis can’t be accepted
