This statistics text for social/behavioral science students focuses on making statistics mathematically unintimidating (single subscript notation throughout). Topics are introduced and discussed in conjunction with exciting, contemporary, real-world examples. Includes ample practice problemsQall completely solved.
r is also known as Pearson's correlation coefficient ( after Karl Pearson - see Chapter 18 ) . • Considering the definitions of Sxx , Sxy and Syy , we can write : sample covariance correlation = ( sample variance of x ) * ( sample ...
For a standard two sample t-test, the signal to noise ratio is called Cohen's d, which is estimated from data as (see Chap. 3): d = . Cohen's d tells you how easily you can discriminate different means. The mean difference is in the ...

Understanding Statistics
With this kind of output, the important piece of information is the significance of the Pearson (SPSS nomenclature for the Pearson chi-square). The goal is essentially the same as above, except in reverse. Whereas we would use 90%, 95%, ...
