Now that it's launching via Apple, companies like Comcast and Verizon may not have as much of a choice to sit out, or pull stunts like locking down access to HBO Go. Our other question is how much it will cost if anyone else offers it, as an official FAQ mentions prices may vary across providers.
Best Answer: The range is the actual measured deviation from the lowest to the highest, without considering how often each observation occurs. The standard deviation considers the deviation from the mean of each observation.All the range tells you is that at least one observation was this far from the norm. The standard deviation tells you how likely an observation will be in a particular range.Microsoft Math will compute a range and a standard deviation for you based on an observation set-you could make up some small sets and look at the resultant figures.he standard deviation tells you how likely an observation will be in a particular range.

The population standard deviation is calculated using =STDEV(VALUES) and in this case the command is =STDEV(A2:A6) which produces an answer of 0.55. The sample standard deviation will always be greater than the population standard deviation when they are calculated for the same dataset. This is because the formula for the sample standard deviation has to take into account the possibility of there being more variation in the true population than has been measured in the sample. Based on their sample of 5 cars, and therefore using the sample standard deviation, the manufacturers could state with 99% confidence that similar cars will do between 14.57 (MEAN-3SD) and 17.87 (MEAN+3SD) kilometres per litre .
