This function calculates the average deviation of the mean or median as a measure of within-group agreement as proposed by Burke, Finkelstein and Dusig (1999). A basic rule for interpreting whether or not the results display practically significant levels of agreement is whether the AD value is smaller than A/6 where A represents the number of response options. For instance, A would be 5 on a five-point response option format of strongly disagree, disagree, neither, agree, strongly agree (see Dunlap, Burke & Smith-Crowe, 2003). To estimate statistical significance see the ad.m.sim function and help files.

`x` |
A vector representing a single item or a matrix representing a scale of interest. If a matrix, each column of the matrix represents a scale item, and each row represents an individual respondent. |

`grpid` |
A vector identifying the groups from which x originated. |

`type` |
A character string for either the mean or median. |

`grpid` |
The group identifier |

`AD.M` |
The average deviation around the mean or median for each group |

`gsize` |
Group size |
