Myra polled twenty-five students in her class to determine the number of movies the students attended at the theater this year.
The results are in the table. She decided to find the mean of a sample using Row 1 and Row 5. Number of Movies Attended Row 1 6 5 2 8 6 Row 2 2 0 4 5 2 Row 3 3 4 3 0 1 Row 4 5 2 6 3 3 Row 5 2 3 2 2 4 What is the mean of her sample?
If you're finding the mean for row 1 and row 5, remember that the mean is the same as finding an average. You would add all the numbers together then divide by how many you added.
Let me show you:
Row 1: 6, 5, 2, 8, 6 Row 5: 2, 3, 2, 2, 4
Add all the numbers from row 1 and 5 together.
You will get a value of 40.
Now divide number by how many numbers you added together, in this case we would divide 40 by 10, because we added together 10 numbers.
