In statistics, learning sample space basically represents the presentation and interpretation of the events of the possible outcomes that occur in a planned learning or scientific investigation. The learning sample space helps to refer all recording of information's are numerical or categorical, as an observation. The learning sample space assists in the following three cases, designed experiments, observational studies, and retrospective studies, the end result was a set of data that of course is subject to uncertainty.
Definition for Sample Space
The set of all favorable combinations of outcomes of a statistical experiment is labeled the sample space and is denoted by the mathematical symbol S.
Each possible outcome of a sample space is labeled a member of the sample space, in other words it is labeled the sample point. The trials of a sample space has a finite number of elements are separated by commas (,) and enclosed in braces ({}).
Thus the: sample space of possible outcomes when a coin is tossed, may be written S = {H, T),
Where, H means that “heads" and T means that “tails,”.
Examples for Sample Space:
Example 1:
Determine the sample space for the event of rolling a die, using the learning sample space.
Solution:
In rolling a die the number that shows on the top face.
The required sample space S1 = {1, 2, 3, 4, 5, 6}.
Example 2:
Determine the sample space for the number is even or odd.
Solution:
The required sample space S2 = {even, odd}.
More than one sample space:
If we know which element in S1 occurs, we can tell which outcome in S2 occurs; however, knowledge of what happens in S2 is of little help in determining which element in S1 occurs. Provides more information than S
Ex: A coin is tossed twice. What is the Sample space?
Sol: The sample space; for this experiment is
S= {HH, HT, TH, TT}.
