You can find the steps for anindependent samples t test here. But you probably don’t want to calculate the test by hand (the math can get very messy. Use the following tools to calculate the t test: How to do a T test in Excel. ...
In this guide, I will explain how to calculate Z-scores by using SPSS, in three simple steps. The process is actually ridiculously easy, it’s just not very obvious within the SPSS interface on how to do it. What is a Z-score? A Z-score, also known as a standard score, represents...

your data is entered into SPSS, you can display useful charts and graphs. SPSS includes the autocorrelation function (ACF), which is for time series data only. Time series data refers to the sequence of values for only one variable. ACF will help the user calculate lags for a specified ...
Then, we identify the number in the middle as the median. If there are even numbers of values, we calculate the mean of the values in the middle to find the median. Median = (4+6)/2 = 10/2 = 5 Mode The mode of a data set is the value appearing most often in the set. Mod...
To calculate the Wronskian for linear functions, the functions need to be solved for the same value within a matrix that contains both the functions and their derivatives. An example of this is W(f,g)(t)=\begin{vmatrix} f(t) & g(t) \\ f'(t) & g'(t) \end{vmatrix} ...
