This is used when a conservative approach is desired and an expected cell frequency is less than 5 in a 2X2 table. - Fisher's exact test It is important to assess the magnitude or strength of a relationship because this assists you with deciding whether or not a variable A causes variable B. True or False - False A Z score of +/-1.96 is equivalent to these values on a normal distribution. - +/-2 standard deviations When examining the relationship between two interval or ration level v...
