Document Summary
Mkt 500 week 8: chapter 12, 13, 14. Frequency- frequencies are the raw numbers in the cell. Raw percentage- cell frequencies divided by the grand total. Column percentage- column cell frequencies divided by its column total. Row percentage- row cell frequencies divided by its row total. Chi-square analysis: allows you to determine if what you observe is what you would expect to occur by chance. The examination of frequencies for two nominal-scaled variables in a cross-tabulation table to determine whether the variables have significant relationship. Asked 100 people if they like to drink iced coffee. Data book code: 1= yes 2= no. Using chi square test, if asymptotic significance (p value) is greater than 0. 05, than it is not a significant difference between both answers. If p value < 0. 05, then worth investigating significant association and have the presence of a relationship (does not tell you anything else in terms of data)
