X-bar Definition 1 x xi n i 1 Probability and statistics - Karol Flisikowski n Sampling Distribution of x-bar How does x-bar behave? To study the behavior‚ imagine taking many random samples of size n‚ and computing an x-bar for each of the samples. Then we plot this set of x-bars with a histogram.

The line between normal and abnormal cognitive changes with age remains indistinct. Normal aging is due to physiological processes over a person’s lifetime‚ in which the biological clock controls development and survival of nerve cells. That does not exclude a spectrum of variable levels of health or a continuum within normal aging‚ as well as between normal and pathological aging. At one end there are individuals with “successful aging” [34]. At the other end‚ we find frail‚ easily incompensated
