      Lenses

      A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

      What is in a lens?

      Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

      Who can create a lens?

      Any individual Connexions member, a community, or a respected organization.

What is an outcome?

Module by: Christopher Chikalimba-Gama

Summary: This module defines what an outcome of an experiment is.

An outcome is one of the possible results of an experiment. It could also mean the result of an event. An outcome to a random experiment is a result to such an experiment. In statistics the outcome of an experiment in which a dice is rolled can be any one of the natural numbers 1 through 6. An outcome is important to a sample space.

The following list consists of a possible outcome of the random experiment examples.

  • Heads
  • Rolled a six
  • The ball numbered 25
  • 45% of calls dropped per minute
  • 2.5 seconds
  • 6.3 minutes

Exercise 1

In the age old myth that buttered toast lands buttered side down, what would be a possible outcome of a random experiment to test this myth?

Solution 1

One possible outcome of the buttered toast random experiment would be that the toast lands buttered side up. Another possible outcome would be that the toast lands buttered side down.

Exercise 2

Suppose one wants to make a call to the insurance call centre to either put up a claim or just an enquiry, what could be the number of outcomes to such an event of making a call?

Solution 2

There would be three possible outcomes to such an event:

  1. the call being successful
  2. the call being put on hold
  3. the call being unsuccessful
