One Sample t Test Framework with Gardening Example (15-3)
The one sample z test is a parametric procedure that tests whether a single sample mean is significantly different than a population mean when the standard deviation of the population (σ) is UNKNOWN. We will learn the research design for the IV and DV, the assumptions for the test, how to

A Gentle Introduction to the One Sample t Test (10-2)
A one-sample t test will allow us to compare a sample mean to a population mean to determine if they are statistically significantly different. This video will introduce you to the fundamentals of the one-sample t test and prepare you for conducting one either by hand or using SPSS. This

Two Tail Hypothesis Test for Difference in Proportions | Statistics
We perform a two-tailed two sample z test for a difference in population proportions. This two proportion hypothesis test will require us to state our null hypothesis and alternative hypothesis, then calculate the pooled proportion to use in our standard error calculation, and then finally

Null and Alternative Hypotheses in Statistics (7-8)
There are two types of hypotheses we need for hypothesis testing: the one we test (the null hypothesis) and the one that use instead if we reject the null hypothesis (the alternative hypothesis). The null hypothesis (H0) states there is no difference between the experimental (sample) mean
