Run a Paired Samples t Test. To run a Paired Samples t Test in SPSS, click Analyze Compare Means Paired-Samples T Test. The Paired-Samples T Test window opens where you will specify the variables to be used in the analysis. All of the variables in your dataset appear in the list on the left side.
A fixed point is a point that does not change upon application of a map, system of differential equations, etc. In particular, a fixed point of a function f(x) is a point x_0 such that f(x_0)=x_0. (1) The fixed point of a function f starting from an initial value x can be computed in the Wolfram Language using FixedPoint[f, x].
Not to be confused with a fixed point where x = f (x) . This article is about stationary points or critical points of a real-valued function of one real variable. For the general notion, see Critical point (mathematics) .f the function is twice differentiable, the stationary points that are not turning points are horizontal inflection points. For example the function has a stationary point at x=0, which is also an inflection point, but is not a turning point.
