EZZE CORRE $29.95 USD PRICE REDUCED TO 19.95

EZZE CORRE is a statistics data analysis utility with 'PROGRAM KEYPADS' which makes it EZZE
to prepare Hypothesis Test, Correlation Analysis and Regression Modelling Reports. In addition it
has a library of sample problems and an easy to understand USER'S GUIDE which take the
mystery out of doing the following:

(I) HYPOTHESIS (Null, Student - t, Chi Square) TESTS OF DATA
The purpose of hypothesis testing is to test the viability of a hypothesis in the light of experimental
data. Depending on the data, the hypothesis either will or will not be rejected as a viable
possibility. Which test, when and how to use them is presented with sample problems to help in
their proper use.

(II) CORRELATION (Pearson) COEFFICIENT
The coefficient calculates the strength of the correlation between up to 5 measured variables with
which one may predict future results or outcomes based on regression analysis of sets of
measured variables.

(III) REGRESSION MODELLING
The program uses Least Squares criteria (by three different techniques) for "Goodness-of-fit to
develop a model and evaluate the model's validity. Regression models are powerful tools for
predicting a score based on some other score. With the model EZZE CORRE estimates exact
scores, called point estimates and intervals of scores(interval estimates) for up to 5 measured
variables (10 relationships).
