variation is the standard deviation of a data set‚ divided by the mean of the same data set. * Z score = x -ms * The Independent part is what you‚ the experimenter‚ changes or enacts in order to do your experiment. The dependent variable is what changes when the independent variable changes - the dependent variable depends on the outcome of the independent variable. * P=000=P<0.001 * Repeated measure = A repeated measures design is a longitudinal study‚ usually a controlled

QNT 561 May 13‚ 13 Gerald Heidt Learning Team Reflection This week‚ we were introduced to the null and alternative hypothesizes. In doing this we were given examples of how to compare two populations by using confidence intervals in order to test the hypothesis. Team A was also introduced to how we can apply these methods to problems more applicable to our professional careers‚ when two population means‚ population proportions‚ or population variances‚ need to be compared. In learning new material
