ConfT1mean(0.461368, 0.2776, 50, 0.95) returns {49, -.2009…, 0.5402…}

ConfT2mean

The two-sample Student’s T condence interval for the dierence of two means. Returns a list containing (in

order):

●

The degrees of freedom

●

The lower bound of the condence interval

●

The upper bound of the condence interval

ConfT2mean(

,pooled,C)

Example:

ConfT2mean(0.461368, 0.522851, 0.2887, 0.2887, 50, 50, 0.95,0) returns

{98.0000…, -1.9844, - 0.1760…, 0.0531…)}

Chi2GOF

Chi-square goodness of t test. Takes as arguments a list of observed count data, a second list, and a value of

0 or 1. If value=0, the second list is taken as a list of expected probabilities. If value=1, then the second list is

taken as a list of expected counts. Returns a list containing the chi-square statistic value, the probability, and

the degrees of freedom.

Chi2GOF(List1, List2, Value)

Example:

Chi2GOF({10,10,12,15,10,6},{.24,.2,.16,.14,.1 3,.13},0) returns {10.1799...,

0.07029..., 5}

Chi2TwoWay

Chi-square two-way test. Given a matrix of count data, returns a list containing the chi-square statistic value,

the probability, and the degrees of freedom.

Chi2TwoWay(Matrix)

Example:

Chi2TwoWay([[30,35,30],[11,2,19],[43,35,35]]) returns {14.4302..., 0.0060..., 4}

LinRegrTConf- Slope

The linear regression condence interval for the slope. Given a list of explanatory variable data (X), a list of

response variable data (Y), and a condence level, returns a list containing the following values in the order

shown:

●

C: the given condence level

●

Critical T: the value of t associated with the given condence level

●

DF: the degrees of freedom

●

: the slope of the linear regression equation

●

serrSlope: the standard error of the slope
