To use the assume mean method for calculating the mean of grouped data, you first need to select a value from the data set that you assume to be the mean. This assumed mean (often denoted as 'A') should ideally be a value that is close to the actual mean to simplify calculations. Here's a question to practice this: Question: The table below shows the marks obtained by 50 students in a test. Calculate the mean marks using the assume mean method. | Marks | Number of Students (f) | | :-------- | :--------------------- | | 0-10 | 5 | | 10-20 | 10 | | 20-30 | 15 | | 30-40 | 12 | | 40-50 | 8 | Step 1: Choose an assumed mean (A). A good choice would be the midpoint of one of the classes, preferably near the center. Let's assume A = 25. Send me the next one 📸
