Two very different distributions of responses to a 5-point rating scale can yield the same mean. Consider the following example showing response values for two different ratings. In the first example (Rating A) the Standard Deviation is zero because ALL responses were exactly the mean value. The individual responses did not deviate at all from the mean. In Rating B, even though the group mean is the same (3.0) as the first distribution, the Standard Deviation is higher.
The retail life cycle concept states that retail institutions--like the goods and services they sell--pass through identifiable life stages: introduction (early growth), growth (accelerated development), maturity, and decline.The direction and speed of institutional changes can be interpreted from this concept.et us examine the stages of the retail life cycle as they apply to individual institutional formats and show specific examples. During the first stage of the cycle (introduction), there is a strong departure from the strategy mixes of existing retail institutions.
Decline. The last of the product life cycle stages is the Decline stage, which as you might expect is often the beginning of the end for a product. When you look at the classic product life cycle curve, the Decline stage is very clearly demonstrated by the fall in both sales and profits. Despite the obvious challenges of this decline, there may still be opportunities for manufacturers to continue making a profit from their product.
