Final answer:
The most commonly required statistics to report are Mean, Median, and Standard Deviation. These measures provide insights into the dataset's average, middle, and variability respectively, and are fundamental in describing the characteristics of the data.
Step-by-step explanation:
The most commonly required statistics to report are B) Mean, Median, Standard Deviation. These measures provide a comprehensive view of the data's central tendency and variability.
- The mean is the average value of the dataset and is sensitive to extreme values or outliers.
- The median is the middle value when data is ordered in ascending or descending order, and it is less affected by outliers.
- The standard deviation is a measure of the spread of data around the mean, indicating how much on average the values differ from the mean.
In a symmetrical distribution, the relationship among the mean, median, and mode is that all three measures will be equal. Utilizing the sample formula for standard deviation, you can calculate the mean and standard deviation for given data, and then determine what number is two standard deviations above the mean.
