Descriptive Statistics - This is statistics which are usually true statistics taken from sample data and they can be analysed by using calculations. For example for a set of temperatures for a month you may want to find the average temperature or the range of temperature.The results can be displayed using graphs to show the data visually.
Inferential Statistics - Inferential statistics is based on a small sample about the population. Conclusions about the population can be drawn from the sample data. It says what the data probably means however it may be an estimate which can be based on other information also. It makes predictions of the whole sample based on some parts of the sample. For example in a manufacturing factory if you measure 3 nails out of a box of 100 nails and all 3 measure 5 cm, you can assume that all 100 nails in the box also measure 5 cm.
