The test assumes that the variances in the two groups are equal. See “Output Options” at the beginning of this section for information on the output storage options.t-Test: Two-Sample Assuming Equal Variances The t-Test: Two-Sample Assuming Equal Variances command calculates the unpaired two-sample Student’s t-test. Excel Reference 539Īlpha Enter an alpha value used to calculate the critical values of the t shown in the output. If no value is entered, a mean difference of zero is assumed.Labels Indicate whether the first row of the Y range and that of the X range include header information. The output includes both the one-tail and the two-tail critical values.Variable 1 Range Enter the input range of the first sample it must be a single row or column.Variable 2 Range Enter the input range of the second sample it must be a single row or column.Hypothesized Mean Difference Enter a mean difference value with which to calculate the t-test. T-Test: Paired Two Sample for Means The t-Test: Paired Two Sample for Means command calculates the paired two-sample Student’s t-test. See “Output Options” at the beginning of this section for information on the output storage options.538 The range must be contiguous.Labels Indicate whether the first row of the Y range and that of the X range include header information.Sampling Method Click the sampling method you want.Periodic Click to sample values from the input range period cells apart enter a value for period in the corresponding box.Random Click to create a random sample the size of which you enter in the corre- sponding box.

Statistical features: Basic statistics:descriptive statistics,normality tests, T-Test/,Fisher F-test, correlation coefficients (Pearson,Fechner),covariation ANOVA (MANOVA,GLM, Latin and Greco-latin squares analysis) Nonparametric statistics: Tables Analysis chi-square test, rank correlations (Kendall Tau, Spearman R, etc.), comparing independent samples (Mann-Whitney U, Kolmogorov-Smirnov, Rosenbaum, Wald-Wolfowitz Runs Tests,Kruskal-Wallis ANOVA.) comparing dependent samples (Wilcoxon Test, Sign Test, Friedman ANOVA, Kendall's Concordance) Cochran Q Test Regression: Linear, polynomial, logistic, stepwise and Cox regression Survival Analysis: Probit-analysis, Cox regression Time series analysis:Moving Average, Auto Correlation and Partial AC, etc. This frees up intellectual urces for analyzing the results, rather than agonizing over who and how processed the data, and if any mistakes were made in the process.
#Statplus histogram how to#
While StatPlus 2007 is a "heavy-duty" professional statistical analysis tool, the interface is so simple that even people who have no knowledge of statistics are capable of processing data, provided they know how to use PC and clear instructions are given. The range of possible applications of StatPlus 2007 is virtually unlimited - sociology, financial analysis, biostatistics, economics, insurance industry, healthcare and clinical research, probability calculations for lotteries and gambling operations - to name just a few fields where the program is already being extensively used.
