c207 OA STUDY GUIDE
Nominal
Just Names that can be counted
Whole quantity, remember, or overall
(color of eyes, sort of automobile)
Ordinal
Names that can be positioned in an order and then counted
Whole quantity, rely, or total
(pinnacle 10 soccer teams, pleasure levels)
Interval
Numbers which have identical periods and an order, however no true 0
Can be added and subtracted (NOT increased/divided)
(shirt size, dates, instances)
Ratio
Numbers which have identical periods and an order, but additionally have a real 0
Can be introduced, subtracted, expanded, divided, and ratioed
(possibilities, cash, charges)
Normal Distribution/Bell Curve
sixty eight.Three % of information inside 1 σ of the suggest
95.Four % of facts within 2 σ of the mean
99.7 % of records within 3 σ of the mean
Intersection
"And, Both, All, Every, In a row"
MULTIPLICATION
Union
"Or, Either, Other"
ADDITION
, Bayes
"Given that"
A, B =occasionsB) =probability of A given B is authentic
P (Bchance of B given A is authentic
P(A), P(B) =the unbiased chances of A and B
Image: Bayes
Regression Keywords:
Relationship, correlation, R-Square, scatter plot
R-rectangular (Goodness of healthy) Keywords:
strength of the connection; 0 Weaker to 1 Stronger courting
Logistic Regression:
The structured variable is binary (Yes/NO or On/Off)
Linear Programming:
Uses Constraints and keywords which might be related to the letter “M”. Mix, decrease,
maximize, optimize
2-Sample T-Test:
Difference amongst 2 facts sets that degree the identical issue; use a bar chart
ANOVA:
Difference amongst 3 or extra (Another) that measure the identical thing; use a bar chart
