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.
The third of the product life cycle stages can be quite a challenging time for manufacturers. In the first two stages companies try to establish a market and then grow sales of their product to achieve as large a share of that market as possible.However, during the Maturity stage, the primary focus for most companies will be maintaining their market share in the face of a number of different challenges.n the first two stages companies try to establish a market and then grow sales of their product to achieve as large a share of that market as possible.
