Hint | Answer |

Variables eg gender, hair colour | |

Variables that are in order eg education status | |

Variables that are equally spaced in order eg pounds sterling | |

If the p value is less than this number it is significant | |

Each person in the population has an equal chance of being chosen for the sample | |

Division of the population into characteristics that are then replicated in division of sample | |

Dividing population into groups, and taking samples from these eg geographic areas | |

probability sampling is | |

samples that don't stem from a random choice | |

Choosing the nth number for samples | |

Researcher sets a quota of people that need asking | |

Each respondent leads to the next | |

Asking respondents who are easy to contact | |

Deriving a theory from data | |

looking for data to prove/disprove a theory | |

Describes a case in terms of a single variable eg Descibes a case in terms of the ditribution of attributes that comprise it such as Gender - number of women,number of men and prop | |

Subgroup comparison - describes a case in terms of two variables simulaneously | |

analysis of three or more variables simultaneously | |

Data collection of different entities in experimental conditions | |

Data collection of the same entities take part in all experimental conditions | |

These represent: The level of fit of the mean to the data, the variability in the data, how well the mean represents the observed data | |

Observed values can be used to test hypotheses using test statistics to calculate whether a result is... | |

Looks at the frequency with which cases fall into each combination of categories - relationships between categorical variables- looks at whether there is any systematic relationshi | |

Looks at the difference between what we observe and what would be likely if there were no difference except that generated by chance | |

Can only use chi-square tests where each cell in the table has an expected value of at least | |

Tells you how strong associations are | |

(Cramer's V) Values between 0 to +/- 0.25 | |
