ratios‚ East Coast Yachts current ratio is below the median industry ratio. This implies the company has less liquidity than the industry in general. However‚ the current ratio is above the lower quartile‚ so there are companies in the industry with lower liquidity than East Coast Yachts. The company may have more predictable cash flows‚ or more access to short-term borrowing. The turnover ratios are all higher than the industry median; in fact‚ all three turnover ratios are above the upper

Central Measures Measures of central tendencies are nothing but the measures to describe the "central" values of a collected sample. For an ungrouped set of data these measures are: the mean‚ the median‚ and the mode. The Mean The arithmetic mean‚ or the simple mean‚ is computed by summing all numbers in an array of numbers (xi) and then dividing by the number of observations (N) in the array. ; the sum is over all i’s. The mean uses all of the observations‚ and each observation affects the

(Prof Bowley) The main objectives of measure of central tendency are To reduce data in a single value. To make easy comparisons between data. There are different types of averages; each has its own business applications. 1. Arithmetic Mean 2. Median 3. Mode 4. Geometric Mean 5.

Blood Pressure – Making a formal inference We often talk about a person’s “blood pressure” as though it is an inherent characteristic of that person. In fact‚ a person’s blood pressure is different each time you measure it. Blood pressure reacts to stress‚ diet and genetics.
