We begin by introducing the concept of median. Then, we walk through the process of calculating cumulative frequency (CF), which helps us locate the median class. You'll learn the role of n, the total frequency, and how to determine whether n is odd or even—a key step in identifying the median position. We also explain the median formula used for grouped data, breaking it down into intuitive steps with examples. Courses on Khan Academy are always 100% free.
