... Inferences About Two Means – Dependent Samples (Matched Pairs – Paired data) A sampling method is dependent when the individuals selected to be in one sample are used to determine the individuals to be in the second sample. Assumptions: 1. The sample is obtained using simple random sampling 2. The s ...

Section 2: Comparing Two Independent Population Means with
... unless the sample sizes are greater than 30. In that case, the populations need not be normally distributed. The comparison of two population means is very common. A dierence between the two samples depends on both the means and the standard deviations. Very dierent means can occur by chance if th ...

Descriptive Statistics and Distribution Functions in Eviews
... These functions compute descriptive statistics for a specified sample, excluding missing values if necessary. The default sample is the current workfile sample. If you are performing these computations on a series and placing the results into a series, you can specify a sample as the last argument o ...

If the data is shown to be statistically significant then the data
... The null hypothesis generally states that there is no significant difference between your two sets of data. If it is accepted, it means that any differences in your data are not significant and probably due to random chance. If the null hypothesis is rejected, it means that there is a significant di ...
