Variability 



Best estimate of spread of scores o Variance (s2) o Refer to slides for equations o S2 = 9 Standard deviation (s) o Square root of variance o Root9 = 3

Normal Distribution 

Many statistical tests are based on the assumption of a normal distribution

 

For exploring and understanding meanings ascribed by individuals or groups o emergent questions and procedures o typically done in participants settings o generation of themes from the particulars o researcher is part of meaning making process o flexibility in how research is represented examples: effect of therapy dogs on patients with anxiety, Collection of qualitative data o Documents – journals, meeting minutes o Audiovisual material – videos, blogs, websites
