The same as the average.
The middle term in a set of data.
The term that means the most.
The median of the upper half.
Upper Quartile or Q3
Extreme numbers compared to the rest of the data.
Highest - Lowest
Add all numbers and divide by the total number of items.
Put numbers in order from least to greatest and take the number in the middle.
Q3 - Q1
1.5 x interquartile range. Subtract from Q1 and add to Q3.
Formula for finding the total number of possibilities, or the Fundamental Counting Principle.
The number of ways the first event can happen times the number of ways the second event can happen, etc.
If you have 5 shirts, 4 pants, and 2 belts this is the total number of outfits you can make.

The probability of an event is defined as...
The total number of favorable outcomes divided by (over) the total number of possible outcomes.
The probability of rolling a 3 OR a 4 on one roll of a die.

WHAT DO THEY ALL MEAN?. Median Is the number that is in the middle of a set of numbers. (If two numbers make up the middle of a set of numbers then the.

ODDS vs. PROBABILITY Odds are a little different than probability. When we calculate probability, we look at the ratio of favorable outcomes to the total.

Probability- the likelihood that an event will have a particular result; the ratio of the number of desired outcomes to the total possible outcomes.
