Data Set- is a number that you must arrange in order from least to greater. 2,3,4,5,6,5,4,5,3,4,5,6,7,5,34,3 hours of studying

2,3,3,3,4,4,4,5,5,5,5,5,6,6,7,34

eg. median of 2,5,6,8,9 is 6

Mode- the frequently occurring number in a set of data

hint: mode and most have 4 numbers

eg. mode of 3,6,7,7,9 is 7

Mean- a measure of a central tendency, the sum of the set of value divided by the number of values in the set

eg. mean of 6,4,8 is 6

add up all the numbers divided that by how many numbers there are.

4,6,8

4+6+8=18

Range-The positive between the largest and smallest values in a data set

Range of 4,5,5,6,9,1,3,5,8,6

1,3,4,5,5,6,6,8,8,9
