A data analyst is examining a dataset of daily sales figures for the last quarter to understand the data's spread. To quickly identify the difference between the highest and lowest sales days, which of the following descriptive statistics should the analyst calculate?
Mean
Mode
Range
Standard deviation
The correct measure is the range, which is determined by subtracting the smallest observed data point from the largest observed data point. This calculation provides the total spread in the dataset. Standard deviation quantifies how far data points vary from the mean. The mean is the average value , and the mode is the most frequently occurring value in the dataset.
