The average and median calculated to have a meaning but ratio calculations have no meaning where one cannot state that 100 degrees Celsius is twice 50 degrees Celsius.
d. ratio- in ratio level of measurement the absolute zero value has a meaning, all statistical calculation of central tendencies and dispersion are meaningful, for example, data containing the number of customers that visit a retail shop, the value zero has meaning and the ratio calculations also has meaning where it can be stated that 20 customers are twice 10 customers.
The mean, mode and median are all measures of central tendencies of data; the mean is determined by adding up all the values in a data set and then dividing the number of observations. In the example, the value of the mean will 27/8 = 3.375
The Median is the middle value of an ordered data set for odd observations or the mean value of the middle two variables for even observations. In the example the median will be 3 +4 = 7, then 7/2 = 3.5, therefore median = 3.5 ...Download file to see next pagesRead More

...Comprehensive Statistics... there are 50 numbers, we can divide these numbers into groups of 10 (5 groups). Next we subtract the lowest number from the highest number (76 — 16 = 60). After this, we will divide the difference by the number of groups that we came up with (60 / 5 = 12). Once we get the class width (12), we add it to the lowest number in order to get the lowest class limit (16 + 12 = 28). If we keep on repeating this step, we can determine all the appropriate class limits (28 + 12 = 40, 40 + 12 = 52, 52 + 12 = 64, and 64 + 12 = 76). Because these are the maximum limits, we have to subtract 1 from each class limit (16 + 12 — 1 = 27, 28 + 12 — 1 = 39, 40 + 12 — 1 = 51, 52 + 12 — 1 = 63). Now that we have worked this out, we can...
