Control limits
Okay kiddo, let's talk about control limits!
Imagine that you're playing a game where you have to throw a ball into a basketball hoop. You're really good at it and you usually make a lot of baskets. But sometimes you miss a shot or two. That's okay, because you're not perfect.
Now, let's pretend that you have a coach who is watching you play and keeping track of how many baskets you make. They notice that you usually make about 8 baskets out of 10. So they draw two lines on a piece of paper: one line at 7 baskets and another line at 9 baskets.
These lines are called control limits. They show the range of baskets that you usually make. If you make fewer than 7 baskets or more than 9 baskets, your coach will know that something is wrong. Maybe you're tired, or maybe you're not focusing. Whatever the reason, your coach will want you to get back to your normal range of 7-9 baskets.
Just like playing basketball, control limits are used in other areas too. For example, if you're making a cake, you might have a recipe that says it should bake for 30-40 minutes. Those are the control limits. If the cake bakes for less than 30 minutes, it might not be fully cooked. If it bakes for more than 40 minutes, it might burn.
So to sum it up, control limits are like lines that show what is normal and expected in a certain situation. If something falls outside of those lines, it might mean that there is a problem that needs to be fixed.
