The four primary measures of central tendency:
Mean, median, mode, range
Mean
The average value of a dataset.
Median
The middle number in an ordered list of numbers.
Mode
The number which occurs most frequently in a data set.
Outlier
A number which is significantly greater or smaller than the rest of the numbers in a data set.
Bimodal
A data set which has two modes.
Range
The difference between the smallest and biggest number in a data set.
Calculate the mean of 12, 4, 13, 8, 22, and 19.
(12+4+13+8+22+19)/6 --> 78/6=13
Determine the median of 5, 6, 11, 14, 6, 9, 13, 6, and 18.

5, 6, 6, 6, 9, 11, 13, 14, 18

9

Determine the mode of 27, 45, 45, 18, 9, 18, 45, 54, 18, 72, 54, 45, 81, 72, and 27.

9, 18, 18, 18, 27, 27, 45, 45, 45, 45, 54, 54, 72, 72, 81

45

Calculate the range of 35, 11, 19, 144, 88, 24, 132, 67, 8, 143, 144, 32, and 50.
144-8=136
Standard deviation
A measurement of how close all data points are to the mean of the data set.
Normal distribution
When most data points are close in value to the mean of the data set
Variance
The average of all distances to the mean squared.
Coordinate plane
A two-dimensional surface with an x and y axis used to graph data.
Ordered pair
Two numbers used to locate a point on a coordinate plane.
Measurement unit

A label given to a physical quantity.

Distance formula
Distance=rate*time
Carlos drove 196 kilometers in 4 hours. Calculate his rate in km/hr.
196/4=49 km/hr
Margarita is traveling on a bus going an average of 72 km/hr for 8.5 hours. Calculate her total distance traveled.
72 km/hr × 8.5 hr = 612 km
Rodrigo went for a walk at a pace of 3.3 km/hr, traveling 6 km total. Calculate his total time walked in hours.
6/3.3=1.82 hours
Roberta rode her bike, going 17 mi/hr for 1.4 hours, and then sped up to go 21 mi/hr for 0.6 hours. Calculate her total distance traveled.
17*1.4=23.8 --> 21*0.6=12.6 --> 23.8+12.6=36.4 mi
A semi-truck uses 74 gallons of gasoline per 1000 miles traveled. Going this rate, calculate the total gallons used for a trip of 3,650 miles.
74/1000=x/3,650 --> 1000x=3,650*74 --> 1000x=270,100 --> x=270.1 gallons
Money word problems
Math equations based on financial exchanges that are explained in the form of a short story.
Marques purchased 19 chairs for $22.40 each. Calculate his total amount spent on chairs.
19*22.40=$425.60
The five steps to solving a word problem:
1) Read the problem, 2) Identity the question, 3) Identify the knowns & unknowns, 4) Look for key words, 5) Solve the problem
