Topology/Analysis: Homeomorphism
Definition If is one-one and onto (1-1 correspondence/bijection) continuous is continuous Then we call a homeomorphism between two metric spaces . The metric space are said to be homeomorphic. Properties and Theorems If f is a homeomorphism between metric spaces , The set Gā is open if and only if the image f(G)ā is open. The…
Rank Correlation and Lines of Regression (Statistics for Psychologists)
Some gossips about mathematicians and a special case of correlation coefficient. We also look at what’s regression, how to apply.
Comparing Two Distributions – Correlation Coefficient (Statistics for Psychologists)
So far we were busy finding one value to describe a distribution, and finding how spread the values are! Now, let’s look at how to compare two distributions!
Measures of Dispersion – 2 (Statistics for Psychologists)
Standard Deviation If is the frequency distribution, then standard deviation, denoted by Greek letter Ļ (sigma) is given by where is the arithmetic mean of the distribution and āf =N . Mean Deviation Standard Deviation Uses absolute value to assure that final result is positive Squares to make all values positive, then takes positive square…
Measures of Dispersion – 1 (Statistics for Psychologists)
Central tendency tells us about a number that describes the data – but – not about how ‘spread’ the data is. Meet the tools to measure the spread of data!
