please explain this in simple language  Properties of Mean . Sum of the deviations taken from the arithmetic mean is zero. Ifthe mean of nobservations an, . is then — i) + _ + (x 3 _ + (x n 2. If each observation is increased by p then the mean of the new observations is also increased by p. Ifthe mean of nobservationsxl, 12, is i then the mean of (Cl I p), (x2 p), (113 p), 3. If each observation is decreased by p then the mean of the new observations is also decreased by p. . is then the mean of —p), (•.r2 — p), (:E3 — p), . , If the mean of n observations , :r3. 4. If each observation is multipled by dwhere p 0) then the mean of the new observations is also multiplied by p. Ifthe mean of n observations Xl, x3.. is then the mean of ptl, pa:2, pans, . pan IS pa. 5. If each observation is divided by p(where p O) then the mean of the new observations is also divided by p. Ifthe mean of n observations an , 12, mg.... is then the mean of — ,

Property 1: If x is the arithmetic mean of n observations x1, x2, x3, . . xn; then (x1 - x) + (x2 - x) + (x3 - x) + ... + (xn - x) = 0. Property 2: The mean of n observations x1, x2, . . ., xn is x. If each observation is increased by p, the mean of the new observations is (x + p).Mean of (x1 + p), (x2 + p), ..., (xn + p) = (x + p). Property 3: The mean of n observations x1, x2, . . ., xn is x. If each observation is decreased by p, the mean of the new observations is (x - p). Property 4: The mean of n observations x1, x2, . . .,xn is x. If each observation is multiplied by a nonzero number p, the mean of the new observations is px.Property 5: The mean of n observations x1, x2, . . ., xn is x. If each observation is divided by a nonzero number p, the mean of the new observations is (x/p). Property 5: The mean of n observations x1, x2, . . ., xn is x. If each observation is divided by a nonzero number p, the mean of the new observations is (x/p).
