Applied Statistics for Distribution Analysis
Comparative indexing/ranking can provide an economical and conscientious process for companies to make important decisions quickly.
 
We can help provide tools and models designed to assist your firm in distribution guidelines or objectives.
 
EXPEV can perform a thorough statistical analysis (including ANOVA and hypothesis testing) to identify any significant biases, from an inter-organizational view and/or demographic standpoint.
Two sample assuming equal variances.
Hypothesis test for Female and Male.
t=2.426319
p=0.01787		 The sample averages
4.18 and 4.76		 are significantly different (p<0.05)
We have REJECTED the null hypothesis that claims the population means are equal and have instead ACCEPTED the research hypothesis using the small - sample unpaired standard error, which assumes equal variabilities and assuming random samples from normal populations.
