Normal Definition & Meaning - Merriam-Webster

The normal distribution is the only distribution whose cumulants beyond the first two (i.e., other than the mean and variance) are zero. It is also the continuous distribution with the maximum entropy for a specified mean and variance. Geary has shown, assuming that the mean and variance are finite, that the normal distribution is the only distribution where the mean and variance calculated from a set of independent draws are independent of each other. WebFor this example question the X-value is your SAT score, 1100. Step 2: Put the mean, μ, into the z-score equation. Step 3: Write the standard deviation, σ into the z-score equation. Step 4: Find the answer using a calculator: (1100 – 1026) / 209 = .354. This means that your score was .354 std devs above the mean.
