For example, if our data are, then the data would be bimodal, with modes of 5 and 3. As such, there are often times when the mode is more than one number. The mode is defined as the most often occurring value in a data set. If there is an even number of data points and thusly there is no single median value, the average of the two values closest to the middle is taken as the median. Therefore, if we were to order our data from lowest to highest, the median would be the value in the middle of that list. The median value of a sample is the value, x median, which is less than ( N - n median)/2 values of x i, and greater than the other ( N - n median)/2 values, where n median is the number of values that equal the median value. , then the calculated sample mean would be ?. Where n is the number of datum, x i, in the sample. Sample verses Population Statistical PropertiesĪ measure of central tendency is meant to give us an indication of the most likely value in our data, or the point around which our data cluster.One of the two main branches of applied statistics is known as descriptive statistics, which simply describe some numerical property of a set of data, with no indication on how that data relate to our hypotheses. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely products of a deranged imagination." Any finite number divided by infinity is as near nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. However, not every one of them is inhabited.
"It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in.
