Think of a parameter like a special rule or instruction you give to a toy robot so it knows what to do. Imagine you have a toy robot that can do different things: dance, sing, or spin. A parameter is like telling the robot exactly how fast to dance or what song to sing. Without these instructions, the robot might not know what to do or might do something else.
Another way to look at a parameter is like a setting on your favorite video game. You know how you can choose different levels of difficulty or pick a character? Those choices are like parameters. They help the game know how you want to play and make sure everything is set up just the way you like it.
Parameters can also be compared to the ingredients in a recipe. When you’re baking cookies, the recipe tells you how much sugar or flour to use. These amounts are parameters because they guide you in making the cookies taste just right. If you change a parameter, like adding more chocolate chips, you get a different kind of cookie.
