STATISTICAL TABLES Cumulative normal distribution (z) is the integral of the standardized normal distribution from −∞to z (in other words, the area under the curve to the left of z). It gives the probability of a normal random variable not being more than z standard deviations above its mean. Values of z of particular importance: z A(z) 1.645 0.9500 Lower limit of right 5% tail 1.960 0
Example 4: Find probability that Z is between -0.82 and 0.82. This is simply two times the area we have found in the previous example (think symmetry!).

In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function, whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would equal

The Normal Probability Distribution is very common in the field of statistics. Whenever you measure things like people's height, weight, salary, opinions or votes, the graph of the results is very often a normal curve. It makes life a lot easier for us if we standardize our normal curve, with a mean
In probability theory, the Fourier transform of the probability distribution of a real-valued random variable is closely connected to the characteristic function of that variable, which is defined as the expected value of , as a function of the real variable (the frequency parameter of the Fourier transform).

bility tables. Probability tables are tables of probabil-ities that have been calculated on a computer. All we have to do is identify the right probability in the table and copy it down! Only one special Normal distribution, N(0, 1), has been tabulated. The N(0, 1) distribution is called the standard Normal distribution. The tables allow us to read off probabilities of the form P(Z < z). 0 z

USING THE Z-TABLE Yıldız Teknik Üniversitesi

Standard Normal Distribution Table The following table gives the proportion of the standard normal distribution to the left of a z- score. Remember that data values on the left represent the nearest tenth and those on the top represent values to the nearest hundredth.
Probability theory began in seventeenth century France when the two great French mathematicians, Blaise Pascal and Pierre de Fermat, corresponded over two prob- lems from games of chance.
To use the table, calculate the number of standard deviations the interval is below the classification cut-off (z). Read the probability of classification below and above the cut-off from left to right. If the interval is above the cut-off the z value is negative and the results are just the opposite (ie. read probability of being below and above from right to left and ignore the table
