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...

Information collected in a numerical form is called - quantitative Which measure of central tendency is at the highest point on a graph? - mode Correlation coefficient tests allow you to determine if a cause and effect relationship is present. - false Data that are categorical but can be rank-ordered in a meaningful way are called: - ordinal If the mean is to the left of the median, what is true? - The distribution is negatively skewed. Which measure of variability is used most of...
