⩥ z test. Answer: a statistical test procedure that uses a sample
statistic having a normal distribution


⩥ t test. Answer: -dependent variable is at the interval/ratio level
-the data are independent not correlated


⩥ One group t test. Answer: • This test compares the mean of your
data set against the hypothesized population mean for your data to
determine if the difference between these two values is "large
enough" to be considered a "significant difference."
