Strengths: The ____ takes into account every number in the data set, so it gives a good overall picture. The ____ is just the most common number, so it’s very easy to find and understand. The ____ is the middle value, so extreme numbers (outliers) don’t change it. This makes it more reliable when there are unusual values. The ____ gives you a quick idea of how spread out the data is, by showing the difference between the highest and lowest values. Weaknesses: The range is affected by ____. One very high or very low number can make the range much bigger, even if most of the data is close together. If no number ____, there is no mode, which makes it unhelpful. If there’s an ____ number (like a very high or very low value), the mean can be pulled too high or too low, which might give a misleading result. The median only focuses on the middle value, so it ____ a lot of the other data, which can sometimes be important.
