Introductory Statistics: What Is A Parameter? (Includes Examples of Parameters and Populations)

A parameter is a number that describes the population, the largest group of "individuals" that we are interested in making inferences on. ("individuals" = "observational units") Because a parameter describes the result of measuring every individual in a large group, it is hard to determine precisely.

The video also provides examples of parameters and the corresponding concept of a "population".
00:00 Introduction
01:06 # of red cars in USA (a parameter)
02:05 parameters are usually unknown
03:32 Examples of parameters (and the populations they correspond to)

Note: I should have said in the video that the population is "the LARGEST group of individuals we are interested in".......The sample is also "a group of individuals we are interested in," but it is a small measurable group. Numbers that describe the sample are called "statistics", and are much easier to know than parameters.

Note: A parameter could also describe something like the true effect of a drug on an individual...and still is hard to know! But because of different reasons than...Generally, parameters represent the truth. The truth is hard to know!

Semester started yesterday and I'm already confused. This helped. Thank you so much!

Thank you for the clear-cut explanation.

Thank you! This is a great video!It is
straightforward and very simple!

So a parameter is the thing that we are required to find out in a given question ....right?

[cristilannlepon]

Thank you.... its really help me....can i used your video for my report?

[Tjackson]

What are two examples though of a population parameter that cannot be calculated but can be estimated?

[nur]

this is very helpful
...I dunno what parameter and thanks you got my problem...

[demente]

This helped soo much thank you, perfect example.

[theresias]

glad I found this video, is it okay if I ask futher question?

[ervandallo]

Thank you for answering my question!!!

I read a statistics book and it mentions that parameters are the actual numbers not the measure.
