Analysis and Presentation of Behavioral Data
... Now you have a frequency distribution of a very large number of differences between sample means when the null hypothesis is true. The name for this set of things is the sampling distribution of the difference between means. The sampling distribution of the difference between means is at the very he ...

JMP® Simulation-Based Empirical Determination of Robust Scale Estimator and Comparison of Outlier Discrimination Performance
... outputs to established specifications. The presence of outliers in the measured values can play havoc with these classical estimators especially for small sample sizes. Robust statistics provide an alternative approach to classical statistical estimators of location and scale. These robust estimator ...

Measures of Spread: Standard Deviation
... most values in a data set fall from the mean? One way to answer this question would be to find the average deviation, or distance, that the data values fall from the mean. So we would add up the deviations to find the total deviation and then divide by the number of data values to find the mean devi ...

Exercise 3 - OCVTS MATES-STAT
... Exercise 4: You are running a political campaign and wish to estimate, with 95% confidence, the population proportion of registered voters who will vote for your candidate. Your estimate must be accurate within 3% of the true population proportion. Find the minimum sample size needed if a) No prelim ...
