 What is Data?
Definition
 observations and measurements you make on a material
Term
 objective, subjective, precision and accuracy
Definition
 objective - existing independently of perceptionsubjective - existing only as perceivedprecision - measurement can be precise and be inaccurateaccuracy - measurement can be correct but not objective
Term
 data matrix
Definition
 rectangular box of numbers
Term
 process of measurement
Definition
 process of assignment value or score to a material
Term
 who proposed the 4 levels of measurement and what year?
Definition
 Stanley Smith Stevens, 1946
Term

Definition
 order by names
Term
 ordinal
Definition
 ranked and ordered

 average, what occurs the most?
Term
 the median
Definition
 the middle
Term
 the mean
Definition
 add all up (sum) and divide by number
Term
 x bar = Σx / n

 S = √ Σ(xi - x bar)2 / n
Definition
 standard deviation
Term
 kurtosis
Definition
 the 'tails' on a graph

 more emphasis on visual displays of data
Term
 histogram
Definition
 no space between the bars
Term
 frequency polygon
Definition
 think 'earth systems'
Term
 triplot

Definition
 what we use for archaeology dig sites
Term
 Ho
Definition
 Null hypothesis- what we DONT want... randomness/ no significance
Term
 H1
Definition
 this is the hypothesis we want!!!
Term
 type | error
Definition
 rejecting a true Ho
Term
 type || error
Definition
 accepting the Ho when it is false
Term
 KS = k * √(n1 + n2) / (n1 * n2)
Definition
 Kolmogorov-Smirnov test Used to compare two cumulative distributions to see whether a sample of data has been drawn from a population which has a particular distribution.
Term
 x2 = Σ (o-e)2 / e
Definition
 Chi Square test It works by testing a distribution observed in the field against some other distribution determined by H0.
Term
 x-axis vs y-axis
Definition
 x=independenty=dependent
Term
 the Correlation Coefficient (r)
Definition
 the measure of extent to which data points are scattered around regression line.
Term
 coefficient of determination r2
Definition
 takes away the - or +
Term
 r = nΣxy - (Σx)(Σy) / √[nΣx2 - (Σx)2][nΣy2 - (Σy)2
Definition
 Product Moment Correlation Coefficient PMCC calculating correlation coefficient   if both variables are measured on interval or ratio scale
Term
 rs = 1 - 6Σd2 / n(n2-1)
Definition
 Spearman's Rank Correlation Coefficient SRCC calculating correlation coefficient if one or both variables are measured on ordinal scale
Term
 inter-siteinfra-site
Definition
 inter = between/landscapeinfra = within/site
Term
 dimensional analysis of variance
Definition
 Look at distributionsover a range of quadrat sizes from the basicrecording unit up to whole sites.
