Drugs that reduce emotionality make big money for drug companies. These drugs undergo extensive testing, some of which is done with animals. One common test of emotionality in rats is the number of fecal boluses that are dropped when an animal is left for 10 minutes in an open field (a 4' x 4' space). Greater emotionality is indicated by more boluses. Imagine that two drugs, aloe and vera were compared. Five rats received aloe and five received vera. The numbers below represent the number of boluses dropped in the open field. Aloe Vera

The effect size index for Data Set 10-8 is?

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
