Multiple Choice

i. Using the ratio-to-moving-average method, dividing the actual sales for a month by the typical seasonal for that month results in a figure that includes only trend, cycle and irregular fluctuations. This procedure is called deseasonalizing the sales. ii. The reason for deseasonalizing a sales series is to remove trend and cyclical fluctuations so that we can study seasonal fluctuations.
iii. Knowing the seasonal pattern in the form of indexes allows the retailer to deseasonalize sales.

Definitions:

Phasic Receptors

Sensory receptors that detect changes in stimulus intensity, adapting quickly and only responding to the onset and cessation of stimuli.

Primary Receptors

Sensory cells or nerve endings that respond directly to stimuli from the environment, such as light, sound, or chemicals.

Secondary Receptors

Molecules or structures in cells that detect signals from primary receptors and help propagate the signal inside the cell, often involved in signal amplification.

Tonic Receptors

Sensory receptors that respond to stimuli over a prolonged period, maintaining the perception of a sensation.
