STANDARD DEVIATION The standard deviation is a popular measure of variability. It is used both as a separate entity and as a part of other analyses‚ such as computing confidence intervals and in hypothesis testing. The standard deviation is the square root of the variance. The population standard devia¬tion is denoted by σ. Like the variance‚ the standard deviation utilizes the sum of the squared deviations about the mean (SSx). It is computed by averaging these squared deviations (SSX/N) and

to “a special sensibility which a creature acquires in its infantile state" (Montessori‚ 1966‚ p.38). Such sensitive periods were first discovered in insects by the Dutch scientist Hugo de Vries‚ but according to Montessori‚ can also be found in children and are very important to consider in teaching. Each sensitive period is a "transient disposition and is limited to the acquisition of a particular trait" (Montessori‚ 1966‚ p.38). Once the sensitive period is over‚ the sensibility disappears due

This time gap is called “lead time.” From past experience‚ the materials manager notes that the company’s demand for glue during the uncertain lead time is normally distributed with a mean of 187.6 gallons and a standard deviation of 12.4 gallons. The company follows a policy of placing an order when the glue stock falls to a predetermined value called the “reorder point.” Note that if the reorder point is x gallons and the demand during lead time exceeds x gallons‚ the

Ana Ortiz Sensorial The Senses The basic five senses that we were all taught are visual (seeing)‚ auditory (hearing)‚ olfactory (smelling)‚ gustatory (tasting)‚ and tactile (touching). Most of the Montessori sensorial activities revolve around these senses. Everything humans do involves using one or more senses. It is through the senses that infants discover the world.
