Algebraic Equation
- answer-An equation that is solved to find the value of an unknown variable.
Averaging
- answer-This type of analysis is appropriate when data is relatively constant over
time.
+ Easy to calculate.
- Assumes little to no change over time.
Basic Line Formula
- answer-Creates a straight line.
y = a + bx
a = y-intercept
b = slope (rise/run)
Bernoulli Trial
- answer-An event that has two possible outcomes: a success or failure.
Probability of success - P(S) = P
Probability of failure - P(F) = 1 - p
Rolling a 3 on a 6-sided die:
P(S) = 1/6
P(F) = 1 - 1/6 = 5/6
Binomial Distribution
- answer-The distribution of the number of successes in a string of Bernoulli Trials.
Bracket Medians
- answer-On a decision tree, you can evaluate continuous uncertainty using this.
, For example, if you could make anywhere from $50,000-$70,000 with one
outcome, you would put the expected values of the .1, .3, .5, .7, and .9 fractiles as
their own branches coming out of an event node/circle.
The EMV would be these values' weighted average, each weighted at 2.
Breakeven Point
- answer-The volume of sales needed to cover fixed costs after accounting for
variable costs.
If a sofa's CM is $200 and fixed costs are $1,000, this is 5 units.
Classical Probability Theory
- answer-If the outcomes 'x' are termed as success, and the total number of possible
outcomes are 'y', then the probability can be calculated as x/y.
The possible outcomes must be mutually exclusive, collectively exhaustive, and
equally likely.
Coefficient
- answer-The number that precedes an unknown variable.
(5)x
Coefficient of Correlation
- answer-Measures strength of linear association (+ or -) between examined
variables.
Notated as r.
Calculated as the sq. root of the coefficient of determination (r^2), or r.
Since it can be positive or negative, this value takes the same sign as that of the
regression model's slope.
Coefficient of Determination
- answer-The percentage of variation in data points that can be explained by our
model.
Notated as r^2.
