Inferential and descriptive statistics have each given very different insights into the exact nature of all of the data that has been gathered. One cannot give the entire picture alone and together; they actually provide a very powerful tool for both the predictions and descriptions as well. The complete study of statistics can actually be categorized into two completely different and main branches as well. These branches are actually descriptive statistics and also inferential statistics. In order to collect a lot of data for any kind of statistical study, a decent population should be defined. The word ‘population’ in this scenario has been known to indicate a group that has actually been designated in order to gather all of the data.

The data or the information as one would say it, is collected properly from the population and this is not necessarily referring to the people. A population can actually be a group of people, a measurement of a type of rainfall in one area in particular or even a batch of batteries indeed.

## Here is some information on descriptive statistics.

- It will give you some information that will describe the data in some manner, indeed. Well, for example, suppose that a shop sells food items that includes pizza, pasta, burgers and steaks. If 100 food items were sold and 50 of that were pizzas, then one description of the data would be that 50% of them were pizzas in the number that they were sold. Some of the measurements in the descriptive statistics have answered the questions which ask how widely dispersed the data would have a lot of different values. You may be wondering about a values indeed. You could be thinking where a particular data value would stand in respect with some of the other values in the data set.
- This would provide a quick method to properly make some comparisons between all of the data sets and also to spot some of the smallest and also some of the largest values and also some trends or even changes over a long period of time indeed. One of the best ways to ensure that you develop a lack for it is by making sure that statistics homework is taken seriously allowing you to understand the concepts better.

## Inferential Statistics

- Suppose you are in need of collecting some data on a very large population and suppose that you want to know what the average height is for the men in the city that you live in and the population is actually in the millions. It is not exactly practical to try and get the height measurements of every single man, can you?
- This is actually where inferential statistics comes into play. It will make inferences about all of the populations by making use of data which is drawn from the population.
