Population and parameters

-
    -

  • Population: The set of all units we want to study;

    • -

  • Parameter: A quantity that summarizes the population (e.g., mean, median, std. dev., quantiles, min, max, proportion);

    -
      -
    • Parameters are constant (not random!);
      • -
    • Parameters are usually unknown;
      • -
    • -

  • Variable: A variable is an attribute of the elements in the population.

    • -
-
-
-

Example: Aquarium

-

An aquarium has 20 fish. We are interested in the average weight of the fish in the aquarium.

-
-
    -
  • Population: 20 fish in the aquarium;
    • -
  • Variable of interest: weight;
    • -
  • Parameter: average weight of the 20 fish in the aquarium (denoted by \(\mu\));
    • -

Sample and statistics

-
    -

  • Random Sample: a randomly selected subset of the population;

    • -

  • Statistic: a quantity calculated based on a sample (e.g., sample mean and sample std. dev.);

    -
      -
    • statistics used to estimate parameters;
      • -
    • statistics are random quantities (they depend on the sample drawn);
      • -
    • -
-
-
-

Example: Aquarium

-
    -

  • Suppose we randomly choose 3 fish from the aquarium to weigh them;

    • -

  • We can calculate the sample mean (denoted by \(\overline{y}\)), to estimate the population mean, \(\mu\).

    • -
-
-
    -
  • The problem is: there are 1140 possible samples of 3 fish we could select. -
      -
    • How close will \(\overline{y}\) be to \(\mu\)?
      • -

  • Exercise: If you take a sample at random, what would be the probability that the mean of your sample is fairly close to the true mean, say between 40 and 46?

    • -

  • Exercise: True or False: Each time we take a random sample we will have a different sampling distribution.

    • -
-
-
-
-

Sampling Distribution

-

The sampling distribution of a statistic, like \(\overline{y}\) and \(\hat{p}\), is the distribution of the value of the statistic across all possible random samples of size \(n\) that could be selected from a given population.

-
-
-

Sampling Distribution

-
    -
  • Some key questions: -
      -
    • What is the centre of the sampling distribution?
      • -
    • How spread is the sampling distribution?
      • -
    • What is the shape of the sampling distribution?
      • -
    • -
-
-
-

Sampling Distribution

-
    -
  • As you can see, the sampling distribution tells us a lot about our statistic. -
      -
    • We could, for example, calculate the probability that our statistic would be to a certain range around the parameter.
      • -
    • -
-
-
-

Sampling Distribution

-
    -
  • But how is this useful if we need to have access to all possible samples? -
      -
    • In this case, we would be better off just checking out the entire population.
      • -
    • -
-
-
-

Sampling Distribution

-
    -

  • Luckily, we do not need to have access to all possible samples to know the sampling distribution.

    • -

  • All we need is a sample! The same sample you use to calculate the statistic will also give you information on the uncertainty of your estimate.

Sampling distribution of \(\overline{Y}\)

-
-

This Applet was developed by Mike Whitlock.

-
- -
-
    -
  • Exercise: Using the applet above, study what happens to the spread of the sampling distribution when the sample size increases.
