Skewed distribution: more informative to use the median. Interested in the range of values in a group (i. e. minimum and maximum values recorded) Interquartile range, between which 50% of all the observations lie. Standard deviation, which is a measure of the average amount individual values differ from the mean of the group; the lower the sd, the smaller the spread of values. Discrete measures: the occurrence of a disease, death, or hospital discharge. Measures of effect and association (how measures are used to determine whether an intervention has an effect on an outcome and the size and direction of this effect)
