Data Management
Organizing information involves understanding various statistical measures such as mode, mean, median, and range. The mode is identified by finding the number that appears most frequently in a data set.

Set of Data: 2,5,6,4,3,8,9 Highest Number:9 Lowest Number:2 9-2=7 Range=7
To get the range, all you need to do is, subtract the highest number by the lowest number. The sum is the range
Range is the difference between the greatest and least number in a set of data.
2 Modes: 3,3,6,7,7,5 Mode=3&7
No Mode: 3,5,8,9,1 No Mode
1 Mode: 5,4,4,8,9 Mode=4
All you need to do to find the mode is, basically just see which number comes the most in the set. If there is 1 number that comes the same number of times as another number than there are 2 modes. If all the numbers come only once than there is no mode.
The mode is the number that occurs the most often in the set of numbers.
With doing the mean: 2,1,3,5,6,7
X,X,3,5,X,X
3+5=8 8÷2=4 4=median
Without doing the mean: 2,3,5,6,8,9,7
X,X,X,6,X,X,X 6=median
To get the median, you first need to put the numbers in order from least to greatest. Then, you cross out all the side numbers, till you get to the middle one which is your median. If their are two left over numbers then you do the mean to it, meaning add first then divide the answer by 2.
The median is the middle number when data is arranged in numerical order.
2,5,6,5,4
2+5+6+5+4= 22 22÷5=4.4
To get the mean, you firstly, need to add all the numbers in the set of data. Then, you divide the answer by how many numbers are in the set. The answer is your mean.
The mean is the average.
