|
Personal Probability |
A subjective belief for how likely an outcome is to occur. |
|
|
Relative Frequency Probability |
The proportion of times an outcome would occur in the long run. |

|
Sampling Distribution |
An orderly arrangement of the values of some sample statistic, showing how often each value would occur in all possible random samples of a given size. |

Point Estimate |
A sample statistic that is our best guess for a single number approximating the population parameter. |
|
|
Confidence Interval |
A range of numbers, computed from sample data, that is almost sure to include the true population number. |

|
Significance |
How confidently a sample result can be generalized to the population. |

|
p-value |
The probability that a relationship as great as the sample result could be found by chance if there were no relationship in the population. |
|
|

A 4-Step process for determining significance, namely (1) Hypothesis, (2) Test Statistic, (3) p-value,and (4) Decision. |
|
|
