extreme value distributions

Identify the incorrect statement(s). I. For an open-ended frequency distribution, Mean is the best average. II. Mean and Midrange are not effected by extremely high or low values in a data set. III. Bimodal is a data set with two modes. IV. Mode is the easiest average ..

Which among the following statement(s) is/are correct? I. An outlier is an extremely high or an extremely low data value when compared with the rest of the data values. II. The mean and standard deviation of a variable are not affected by an outlier. III. The..

Random Variable and Probability Distribution - If is often very important to allocate a numerical value to an outcome of a random experiment. For example consider an experiment of tossing a coin twice and note the number of heads (x) obtained. Outcome : HH HT TH TT No. of heads ..

If is often very important to allocate a numerical value to an outcome of a random experiment. For example consider an experiment of tossing a coin twice and note the number of heads (x) obtained. Outcome : HH HT TH TT No. of heads (x) : 2 1 1 0 x is called a random variable, which can as..

A discrete random variable assumes each of its values with a certain probability. Let X be a discrete random variable which takes values x 1 , x 2 , x 3 ,x n where p i = P{X = x i } Then X : x 1 x 2 x 3 x n P(X) : p 1 p 2 p 3 p n is called the probability distribu..

Let S be a sample space associated with a given random experiment. A real valued function X which assigns to each w i S, a unique real number, X( w i ) = x i is called a random variable . Two types of random variables are 1. Continuous random variable, 2. discrete ra..

Maxwell's Speed Distribution Law - The rms speed of an oxygen molecule in a sample at 300 K is about 480m/s. This does not mean that the speed of each molecule is 480 m/s. Many of the molecules have speed less than 480m/s and many have speed more than 480m/s. Maxwell derived an equation g..

Which of the following statement(s) is/are true ? I. Mode is the measure of central tendency used in exploratory data analysis (EDA). II. Extremely low data value in the data set can be considered as an outlier. III. Percentiles are the same as percentages. => II only or I, II a..

Find the value of - 6(12 - 3) using the distributive property. => - 54 or - 55 or - 56 or - 52..
