c207 OA STUDY GUIDE
Nominal
Just Names that may be counted
Whole wide variety, matter, or total
(colour of eyes, kind of vehicle)
Ordinal
Names that can be located in an order after which counted
Whole variety, matter, or overall
(pinnacle 10 soccer groups, delight degrees)
Interval
Numbers that have same periods and an order, however no genuine zero
Can be delivered and subtracted (NOT elevated/divided)
(blouse size, dates, instances)
Ratio
Numbers which have equal intervals and an order, however additionally have a true 0
Can be introduced, subtracted, increased, divided, and ratioed
(percentages, cash, rates)
Normal Distribution/Bell Curve
68.Three % of information within 1 σ of the suggest
95.4 % of statistics inside 2 σ of the suggest
ninety nine.7 % of information within three σ of the imply
Intersection
"And, Both, All, Every, In a row"
MULTIPLICATION
Union
"Or, Either, Other"
ADDITION
, Bayes
"Given that"
A, B =eventsB) =possibility of A given B is realA) =probability of B given A is true
P(A), P(B) =the unbiased chances of A and B
Image: Bayes
Regression Keywords:
Relationship, correlation, R-Square, scatter plot
R-square (Goodness of fit) Keywords:
power of the connection; 0 Weaker to 1 Stronger relationship
Logistic Regression:
The based variable is binary (Yes/NO or On/Off)
Linear Programming:
Uses Constraints and keywords which can be associated with the letter “M”. Mix, decrease,
maximize, optimize
2-Sample T-Test:
Difference among 2 records sets that measure the same element; use a bar chart
ANOVA:
Difference among three or more (Another) that measure the same element; use a bar chart
Chi-Square:
