Problem
The numbers of faulty products returned to an electrical goods store each day over a 21 day period are: 3 4 4 9 8 8 6 4 7 9 1 3 5 3 5 9 8 6 3 7 1 a. - a** For this data set, find: - i** the mean - ii** the median - iii** the mode. b. - b** On the 22nd day there were 9 faulty products returned. How does this affect the measures of the centre?Intuitive explanation
This is about summarizing and describing a distribution using statistics. Rather than treating these 21 numbers as a jumble, you'll organize them (often in a frequency table or stem-and-leaf plot) to find the center, spread, and shape of the data—things like the median, mode, and range that reveal what a "typical" day looks like and how much variation exists. The key insight is that a few well-chosen numbers can tell you the whole story of what happened over the month.
