Definition | Word |

Where individuals or groups are more likely to take part in a research project than others. | |

A large fraction of those sampled fails to respond. | |

Anyhitng that influences responces. | |

Sampling methods that tend to overephasize some characteristics of population. | |

The entire group represented by the data. | |

Making sure the population is an average, | |

Size of a population. | |

Sample of the entire population. | |

Any summary found from the data. | |

Each combonation of people has an equal chance of being selected. | |

A sample that reflects the corresponding parameters accurately. | |

Average represented by 'mu'. | |

Variability represented by 'sigma'. | |

Splitting the population. | |

Trial run of the survey you plan to give a larger group. | |

A portion of the population is not sampled. | |

Individuals who are conveniently available. | |

A study with no manipulation of factors have been applied. | |

An observational study in which subjects are selected and then their previous conditions or behaviors are determined. | |

An observational study in which subjects are followed to observe future outcomes, | |

Manipulates factor levels to create treatments. | |

A variable whose levels are manipulated by the experimenter. | |

The experimental units assigned to a baseline treatment level, a null, or a placebo treatment | |

A treatment known to have no effect, administrated so that all groups experience the same conditions | |

when the probability comes from the long-run relative frequency of the event's occurrence | |

When the levels of one factor are associated with the levels of another factor in such a way that their effects cannot be seperated. | |

Any individual associated with an experiment who is not aware of how the subjects have been allocated to treatment groups. | |

Two events that share no outcomes in common | |

when one event occurs that does not change the probability that the other event occurs | |

between 0 and 1, reports the likelihood of an event's occurrence | |

If A and B are disjoint events, then the probability of A or B is P(A U B) = P(A) + P(B) | |

When the probability is subjective and represents your personal degree of belief | |

states that the probability of the entire sample space must be 1 | |

Sample must be at least 10% of the population | |

requiring events to be independent | |

a probability that takes into account a given condition | |

a display of conditional events or probabilities that is helpful in thinking through conditioning | |

the collection of all possible values and the probabilities that they occurr | |

states that the binomial probability model is approximately Normal if we expect at least 10 successes and 10 failures | |

states the data values must be sampled randomly, or the concept of a sampling distribution makes no sense | |
