Document Summary

Chapter 13: data processing, fundamental data analysis, and the statistical testing of hypotheses. One-way frequency tables: the most basic level of tabulation that indicates the percentage of response frequency: cross-tabulation: filtering data based on variables tested, bivariate cross-tabulation cross tabulates two variables, multivariate cross-tabulation cross tabulates more than two variables. Only interval and ratio scales can be used in statistical testing: mean, median, mode, standard deviation, skewedness, variance, range. The higher the significance level to do: the more likely you are to reject the null hypothesis (which is what you want, the more likely you are to be wrong in rejecting it (making a type i error) 4, calculate the value of the test statistic: convert the sample result into a z-value and compare it to the critical value (z-value from the level of significance: state the conclusion: based on the comparison above .
