ISDS 361A Study Guide
Chapter 7
* Discrete Random Variable = can take countable number of values / Continous = values are uncountable * Probability distribution: a table, a formula, or graph that describes the values of a random variable and the probability associated with these values. * Requirements of Probabilities P(x) = 1 ; Prob must lie between 0 and 1 * Population Mean = E(x) = (x)P(x) Population Variance =( x to the second power)P(x) – Mean squared * Standard Deviation = the square root of variance

* Law of Expected Value: E(c)=C , E(x+c) = E(x) + C, E(cX) = cE(x) * Laws of Expected Value = V(c)=0 , V(x+c) = V(x), V(cX) = c^2V(x) * Bivariate or Joint Probability Distribution: a table, formula, or graph that describes the joint probabilities for all pairs of values of x and y (two random variables) * Binomial Probability Distribution:

* P(X=x) = P(X) = number of trials / (#ofsuccesses)(#offailures) X (Success rate)^#ofsuccesses(Fail rate)^(#offailures) * Mean of BPD = NP (Number of trails)(Success Rate) Variance = NPQ (FailRate) SD = Square Root Variance * At least N = P(x>or equal 16) = 1-P(x < or equal to 15) P(x<14) =P(x< or equal 13) P(x>12) = 1 – P(x< or equal 12) * P(10<orequal X <orequal 21 P(X<orequal21) – P(X<orequal9) * Poisson Probability Distribution = the probability of X events/Successes in a specific interval. Chapter 6

* Conditional Probability = P(A/B) = P(A and B) / P(B) , Two events are related; A given B * P(A) + P(A^c) = 1 (COMPLEMENT)
* Sample Space = All Possible Outcomes
Chapter 2
* Categorical or Qualitative Variable = diff. categories are distinguished by some non-numeric characteristics * Numerical or Quantiative = #’s represents counts or measurements (weights, #ofpets, annual income) * Ratio Level/Interval = Observations are numerical (height, weight, prices) * Nominal Level = observations are categories, names,...

...Littlefield Technologies Game Strategy- Group 28
I. PROJECT MANAGEMENT: We can apply multiple project management concepts to planning the project, scheduling the project, and controlling the project. First, the project was planned and scheduled by setting a goal of completion. Considering the group’s total allotted time, our goal was to have the description of the game strategy completed 48 hours before the deadline, and to work collaboratively on the statistical spreadsheet 24 hours...

...ISDS CASE 16.2 2012
Executive Summary:
We believe that utilizing Regression Analysis will provide us with enough data to make an accurate prediction. Regression Analysis is simply put using the value of one dependent variable Y based on the data of other independent variable(s) X. To conduct a Regression Analysis, we need to input data from two variables and produce a Regression equation that describes the relationship between the dependent variable and the independent...

...Applying Malcolm Knowles Andragogy Model to ISD
Abstract
The way that an instructional designer defines learning and what is believed about the way learning occurs plays an important role in situations where the facilitator wants to make a change in how people do a job or they need to learn something new on the job. This paper focuses on Malcolm Knowles adult learning assumptions and how to apply them in instructional strategies and techniques for facilitating...

...Kookai, a French fashion label founded in 1983 by Jean-Lou Tepper, Jacques Nataf and Philippe de Hesdin. In 2004 their Australian clothing line ran a campaign asking the question “What would the world be without women?” In one particular advertisement we see a average man dressed in women’s clothing and holding a baby, with the question “What would the word be without women?”
However the Australian clothing may have had the best intentions at heart to empower women and to challenge culture....

...How to Read Literature Like a Professor Essay
By: Naomi Brooks
Introduction
How'd He Do That?
Professors use memorization when reading a new book because they are always
looking for correspondences between new and old books. Everything is a symbol until proven
wrong, since symbolism is used when they are reading, thinking, and asking questions such
as: is this an analogy, metaphor, or what might it signify? With time professors remember ...
