What type of risk is measured by standard deviation?
In terms of stock analysis, volatility.
The annual precipitation for one city is normally distributed with mean of 38.9 inches and a standard deviation of 3.3 inches Find the 20th percentile?
45.665 inches Type your answer here... what is the answer??
Is mean medain standard deviation calculated as continuous data in statistics?
You can calculate the mean, median, and std dev for discrete or continuous data. Each type has its own set of formulas.
How do you derive the mean deviation about the mean of the pareto type 1 distributions?
Easy. The mean deviation about the mean, for any distribution, MUST be 0.
What is the definition of T score?
T score was originally given to a type of normalized score based on a group of unselected pre-adolescents. Notwithstanding, it has come to refer to any normally distributed standard scores that has a mean of 50 and a standard deviation of 10. L F C
What is measure of variation?
A measure of variation, also called a measure of dispersion, is a type of measurement that details how a set of data is scattered from a central or neutral point of origin. Range, variance and standard deviation are three measures of variation that are commonly used.
Which type of measure of dispersion is mostly used standard deviation or variance?
They are effectively the same but the standard deviation is more popular because the units of measurement are the same as those for the variable.
What type of risk is measured by standard deviation?
In terms of stock analysis, volatility.
How many standard deviation tend to cover the entire range of scores in a distribution?
Type your answer here... It depends what percentage of the total data you want to embrace. 99.73% of the total distribution lies between minus to plus 3 standard deviations. That's usually the benchmark range.
How do you perform Geometric standard deviation in Excel?
I just had this problem myself. A simple solution, not 'the solution' (as i believe you can pay for this function to be added to excel), is as follows: (NB. This can be checked with reference to the GEOMEAN function).e.g. your data is in column A (A3-A33)in cell B3 type =LN(A3) (i.e. the natural log)copy and paste down to B33.In B34, calculate the standard deviation of the loged numbers i.e. =STDEV(B3:B33)In A34 type =EXP(B34) This is your geometric standard deviation!!You can check this method with ref. to the GEOMEAN function.Take the mean of column B. i.e. in cell B35 type =average(B3:B33)In cell A34 type =EXP(B34).This should returen the same answer as =GEOMEAN(A3:A33)There is an error in the above mentioned function which is://In B34, calculate the standard deviation of the loged numbers i.e. =STDEV(B3:B33)Here do not calculate the STDEV(b3:b33) instead, calculate the =AVG(b3:b33)
Suppose lifetime of certain type of car batteries are normally distributed. Brand A has a mean lifetime of three years and a standard deviation of six months. Brand B has a mean lifetime of 36 months and a standard deviation of four months?
Brand A

Two liquid A and B on mixing produce a warm solution which type of deviation from Raoult's law does it show?
it shows negative deviation
Concept of normal and abnormal behavior in psychology?
Normal behavior is basically behavior that is socially acceptable. Everyday type stuff. Abnormal is what lies outside that standard deviation. Things such as schizophrenia, bipolar, and other psychological disorders are classified as abnormal.
How do you derive the mean deviation about the mean of the pareto type 1 distributions?
Easy. The mean deviation about the mean, for any distribution, MUST be 0.
