WALT: Find and validate data measures. Eg Mean,Median,Mode and Range from appropriate displays.

Median- The middle number in the set of data. Eg: 1,2,3,4,5. 3 is the middle number.

Mode- The number you see the most. Eg: 1,2,2, 3,,5. The most numbers shown is 2.

Mean- You calculate all of the data and divide it by how many numbers there are. Eg: 1+2+5+7+10+9=34 and then you divide 34 by 6 and that equals 5.6. Average.

Range- You take the highest number and take away the lowest number. Eg: 1,5,8,10. So you go 10-1=9
