Applied Probability and Statistics - C955
Whole Number - ANSWER: a number without fractions; no negitives
Integer - ANSWER: can be either a positive number, a negative number, or zero
Rational Number - ANSWER: can be expressed as a fraction
Real Number - ANSWER: any number that can be placed on the number line, whether
that be negative or positive, fraction or decimal
GCF - ANSWER: Greatest Common Factor. The largest number that can divide each
number from a set of numbers without a remainder.
Ex. The G.C.F. of 8 and 12 is 4.
prime factorization - ANSWER: Breaking down a composite number until all of the
factors are prime
Factors - ANSWER: Numbers that are multiplied together to get a product
interval notation - ANSWER: A notation for describing an interval on a number line. The
interval's endpoint(s) are given, and a parenthesis or bracket is used to indicate whether
each endpoint is included in the interval.
Prime Numbers - ANSWER: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29
Celsius to Fahrenheit - ANSWER: F=C×9/5+32
Fahrenheit to Celsius - ANSWER: C=(F−32)×5/9
least common multiple - ANSWER: The smallest multiple (other than zero) that two or
more numbers have in common.
Table spoon to Ounce - ANSWER: 1 Tbs = .5 oz
teaspoon to table spoon - ANSWER: 3 tbs = 1 Tbs
Ounce to cup - ANSWER: 8 oz = 1c
Tablespoon in a cup - ANSWER: 16
, Liter to Gallon - ANSWER: 1 Liter = 0.264172 Gallons
Coefficient - ANSWER: number in front of a variable
Degree - ANSWER: highest exponent on a Variable
Linear Equation - ANSWER: an equation whose graph is a straight line(all vars have a 1
exponent)
Principal of Equality - ANSWER: Everything you do on one side of the = you do the
same on the other.
Slope - ANSWER: M = rise/run = (y2 - y1) / (x2 = x1)
slope-intercept form - ANSWER: y=mx+b, where m is the slope and b is the y-intercept
of the line.
Point Slope form - ANSWER: y-y1=m(x-x1)
Linear Inequalities - ANSWER: When you multiply or divide by a negative you switch
the direction of the sign.
quantitative variable - ANSWER: takes numerical values for which arithmetic operations
such as adding and averaging make sense
Categorical Variables - ANSWER: Data that can be placed in a category but can not be
calculated directly
Mean - ANSWER: average
Median - ANSWER: the middle score in a distribution; half the scores are above it and
half are below it
Mode - ANSWER: the most frequently occurring score(s) in a distribution
Quartiles - ANSWER: Values that divide a data set into four equal parts
interquartile range - ANSWER: IQR = Q3 - Q1, The middle half data points
Outlyers - ANSWER: Below Q1-1.5(IQR) and Above Q3+1.5(IQR)
standard deviation - ANSWER: a measure of variability that describes an average
distance of every score from the mean, 68-95-99.7 Rule
explanatory variable - ANSWER: a variable that we think explains or causes changes in
the response variable
