quantitative data - Answer Quantitative data consists of data values that are numbers, representing quantities that can be counted or measured. The Empirical Rule - Answer According to The Empirical Rule, approximately 68% of the data points in a dataset will be within 1 standard deviation of the mean. 95% of all values are within 2 standard deviations of the mean. Normal distribution - Answer In a normal distribution data is symmetrical, so the mean, median, and mode are all equal. mea...
