Z, or z, is the twenty-sixth and final letter of the modern English alphabet and the ISO basic Latin alphabet.Its usual names in English are zed (pronounced / ˈ z ɛ d /) and zee / ˈ z iː /, with an occasional archaic variant izzard / ˈ ɪ z ər d /. How to use the z table Use the Z- table to find where the row for 1.5 intersects with the column for 0.00, which is 0.9332.
The Z score itself is a statistical measurement of the number of standard variations from the mean of a normal distribution. The Z-score value can either positive or negative indicating that sample lies above or below the mean by a measure of standard deviations. What is a Negative Z-Score? This is a basic video to show you how you can read the standard normal z table to find proportion of area under the standard normal curve.

Using the Z-table Go to the row that represents the ones digit and the first digit after the decimal point (the tenths digit) of your z -value. Go to the column that represents the second digit after the decimal point (the hundredths digit) of your z -value. Intersect the row and column from Steps 1 and 2. CPU-Z tools. Moving on from the tabs, at the bottom of the CPU-Z window you'll see a 'Tools' button. Click the dropdown arrow next to it to bring up several useful features. Z scores (Z value) is the number of standard deviations a score or a value (x) away from the mean. In other words, Z-score measures the dispersion of data. Technically, Z-score tells a value (x) is how many standard deviations below or above the population mean (µ).
Example 1: Find probability that Z is between 0 (mean) and 1, i.e. P(0 < Z < 1). You can read directly the probability from the table. Look at the intersection of row with 1.0 and column with 0.00 decimals. The value at the intersection represents P(0 < Z < 1) = 0:3413.
A file whose name ends in.Z,.z,.gz or.bz2 has been compressed, so it takes up less disk space. Unfortunately, you cannot read compressed files the way you do normal files. You must first expand, or uncompress, the files. How you do that depends on the program used to compress the file in the first place.
