### Leo's Measures of Central Tendency

10:52 PM

Mean

• put raw data into ascending order
• add all numbers to get sum
• divide sum by how much numbers there are
• if you have an outlier it changes the mean
• put raw data into ascending order
• find the middle number
• if there is 2 numbers left add and divide by 2
• if there is an outlier, median is the best way to find the average

• put raw data into ascending order
• most common data
• you can have more than 1 mode
• you can have no mode

Range

• put raw data into ascending numerical order
• largest data minus the smallest data

Here is a great video explaining MMM

hey leomar! good job! haha :D but you forgot to attach a link to the median and mode, and you're suppose to attach a link that explains the mean, not a game. :P just wanted to let you know. :P but still, good job!
