Descriptive statistics o :## describe a sample Inferential statistics o :## make inferences about a population from a sample What are the three measures of central tendency? o :## mean, median, and mode When is the mean not the best measure of central tendency? o :## when there are outliers; they will skew the mean When is the mode the most useful measure of central tendency? o :## when describing frequency data Range o :## the distance between the lowest and highest scores (taking in...

scatter plot ~ way to visualize relationship between 2 quant variables, helps show correlation normal distribution ~ bell curve, mean, med, mode equal negatively skewed ~ tail to left, mean is smallest value, then med, then mode positively skewed ~ tail to right, mean is highest value measures of central tendency ~ single numerical value that is considered most typical of the values of quant. variable (mean med, mode are most common used) point estimation ~ involves us...

EXST 2201 FINAL EXAM QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS GRADED A++ Why is it important to look at the shape of a column of data before interpreting any statistics? To see if the data is unimodal, symmetrical, and without any exceptions. Why look at a chart to get shape information instead of looking at the data values themselves? A chart is needed to summarize the shape characteristic so that we can see it. Match the two meanings below with their appropriate column titles in a ...
