probability distribution - In probability theory and statistics, a probability distribution identifies either the probability of each value of an unidentified random variable (when the variable is discrete), or the probability of the value falling within a particular interval (when the variable is continuous). The probability distribution describes the range of possible values that a random variable can attain and the probability that the value of the random variable is within any ( measurable) subset of that range. When the random variable takes values in the set of real numbers, the probability distribution is completely described by the cumulative distribution function, whose value at each real x is the probability that the random variable is smaller than or equal to x. The concept of the probability distribution and the random variables which they describe underlies the mathematical discipline of probability theory, and the science of statistics. There is spread or variability in almost....

  UCSB Political Science 104 Recoding Variables   You usually want to recode variables when you want to go to a lower level of measurement (from interval to ordinal for example). You can do this by telling SPSS to change old values of your variable into a new value.

Question : 1. measures numerical variables 2. measures variables that have a logical order 3. measures variables that have equal units between each point on the scale 4. measure variables that have a true zero point My guess would be # 3, but I am not sure, thanks for looking

Answer : I'm pretty sure the answer is #4. Temperature is an example of this... the zero for Celsius is not the same as it is for Farenheit (spelling?). These are interval scales I'm pretty sure. (In reality temperature does have a natural zero if you consider the Kelvin scale, but they don't mention that in stats class). Is this a coursecompass class your taking? I've helped people w/ that before. Oh, if you're taking stats, here's a good resource for you: http://www.tutor-homework.com/statistics_tables/statistics_tables.html Take care, David

Question : Okay so suppose the probability density function of a continuous random variable X is f(x)=1/8 where -2 x 6. By using geometry: a) what is the probability that X takes on values less than 0? b) what is the probability that X takes on values greater than 4? c) what is the probability that X takes on values in the interval (0, 4)? I'd appreciate if you tell me how you got to the answer so I'll know how to do it myself.

Answer : So you have the following: Let y = f(x) = 1/8. Given the interval interval: -2 less than or equal to x ; 6 greater than or equal to x. Graphically I draw a rectangle that has a height of 1/8. The width is 8 because of the interval and since 6 - (-2) = 8. Note: For the problems I think you can take the area of the rectangles given the specific intervals. For example: I took the area of the rectangle from -2 to 0 and got an answer of 1/4, since (1/8) * (2) = 1/4. You may need to be careful since you are dealing with open intervals. I strongly urge you to check my first answer though.
