📊 Topic Summary
Line plots are a fantastic way to visualize data! They use a number line to show how often each value occurs. But sometimes, you'll see numbers that are way bigger or smaller than the rest – these are called outliers. They 'lie outside' the main group of data. Gaps, on the other hand, are empty spaces on the number line where no data points fall. Finding outliers and gaps helps us understand our data better and identify unusual patterns.
