- Can be the mean, median or mode
- Data set is a group of numbers that you must arrange in order from least to greatest
- 2, 3, 4, 5, 6, 5, 4, 5, 3, 4, 6, 7, 5, 34, 3
- 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 7, 34
Median- the middle number in a set of data after the data have been arrange in order
Median of 2, 5, 6, 8, 9, is 6
Medina 1, 3, 6, 8, 9, 10 is 7
6+8=14
14/2=7
Mode- the most frequently occurring number in a set of data
- Mode and most both have 4 letters and mo
- Mode of 3, 5, 7, 7, 9, is 7
- Mode of 2, 2, 4, 6, 6, 11 is 2, 6
- Mode of 1, 2, 3 5, is no mode
- Mode of 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, is no mode
Mean- a measure of central tendency
The sum of a set of values divided by the number of values in the set
Mean of 6, 4, 8, is 4
4, 6, 8
4+6+8=18
18/3=6a
- Range - the positive difference between the largest and smallest values in a data set range of 4, 8,56, 9, 1, 3, 5, 8, 6, is 8
1, 3, 4, 5, 5, 6, 6,8, 8, 9
9-1=8 mean,
-2, -7, -1, -4
-7, -4, -2, -1
(-1) - (-7)=6
outlier -a value that is much larger of smaller then the other data value the data set may have then 1 outlier or zero outliers
Outliers for- 1, 67, 68, 67 ,64, 35, 100 are 1 and 100
Find mean, median, mode, range and outliers for the following data sets
18, 19, 79, 17, 20, 12 - Mean
14, 14, 16, 15 1, 16 - Median
98, 202, 99, 91, 2, 95, 89 ,88 94 - Mode

Good job Alexia! You explained the definition for everything. But I suggest you add some more colors to your scribe.
I also found a link that you should put:
