But I do not know whether the difference is statistically significant. How to test this significance and report the t-value? Another question: When I run regression for two groups, I get two coefficients, I know the difference, but how to test the significance for this difference and report...
The presence of spatial autocorrelation in the two variables, however, can affect the statistical significance and the interpretation of their degree of correlation. In this paper, we compare different approaches that have been proposed to solve this problem: a parametric test that corrects for the ...

Focussed Learning Procedure Used to Test for Significance For any statistic we are calculating (e.g., a ‘t’ statistic, a chi-square statistic, a Mann-Whitney ‘U’-statistic, a Spearman’s Rank or Pearson’s Product-moment Correlation Coefficient), the procedure is the same. 1. Decide ...
An experiment is designed and conducted to investigate how persons make sense of a specific case and determine significance in a screening and scoping context.The experiment indicates patterns in the test persons' sense-making, including important differences in the way individuals screen and scope. ...
