**A Stem and Leaf diagram is when there is a line and numbers on the left and right hand side. If there was a 1, then a line, then a 2. That could mean 12 mins. In the survery up the top there is 7 people that took part as there is 7 numbers on the right.**

**Remember :**

When doing a Stem and Leaf diagram you need to remember a key!

If you had a set of numbers and you were asked to put them in a Stem and Leaf diagram, first of all you would see which was the highest and lowest number by looking at the ten units. Your lowest number might be 19 and your highest number might by 67. Then you would draw a line and on the left side write the numbers from the lowest number to the highest number but only the tens. So, if your numbers were 19 and 67. Then the 1 would go on the left and the 9 on the right in the same colum. Then the 2, 3, 4, 5 etc.......... Until you get till your highest tenth number. After that you would look at the numbers and see what tenth it is. Go to that number on the left, whatever the unit is yo put it on the right. This happens until all the data has been put in. Then you would do it again but the thing you would change would be that on the right hand side you but those numbers in order. Then cross the first one out. Remember a key!
