Question

what is the range (A)sum of the highest and lowest observation , difference of highest and lowest observation, product of higher and lower observation none​

Answer 1

The difference between the highest and lowest observations in a given data is called its Range. ... When the given data is arranged in ascending (or descending) order, then the middle most observation is the median of the data.

Answer 2

Answer:

Step-by-step explanation:

• Measures of average such as the median and mean represent the typical value for a dataset. Within the dataset the actual values usually differ from one another and from the average value itself. The extent to which the median and mean are good representatives of the values in the original dataset depends upon the variability or dispersion in the original data. Datasets are said to have high dispersion when they contain values considerably higher and lower than the mean value.
• In figure 1 the number of different sized tutorial groups in semester 1 and semester 2 are presented. In both semesters the mean and median tutorial group size is 5 students, however the groups in semester 2 show more dispersion (or variability in size) than those in semester 1.
• Dispersion within a dataset can be measured or described in several ways including the range, inter-quartile range and standard deviation.
• The Range
• The range is the most obvious measure of dispersion and is the difference between the lowest and highest values in a dataset. In figure 1, the size of the largest semester 1 tutorial group is 6 students and the size of the smallest group is 4 students, resulting in a range of 2 (6-4). In semester 2, the largest tutorial group size is 7 students and the smallest tutorial group contains 3 students, therefore the range is 4 (7-3).
• The range is simple to compute and is useful when you wish to evaluate the whole of a dataset.
• The range is useful for showing the spread within a dataset and for comparing the spread between similar datasets.
