In calculation, you can find the value of √3 and √2 then you can subtract it. There will be a irrational. On subtracting we will have the number which is either terminating or non terminating repeating. Okay..

These for measure are the mean ,mode,median and range 1.The median is a middle number of your data set when in order from least greatest

0Thank You

Yogita Ingle 4 years, 1 month ago

These mathematical terms can be explained by use of the following results that show the length of time in seconds a group of children took to swim a length:

Mark	Susan	Rita	Rebecca	Hannah	Robert	Matthew
9	11	9	15	12	9	10

The mode is the value that appears most often in a set of data. In this case, the mode is 9 seconds.

The mean is the total of all the values, divided by the number of values. To find the mean, we add up all the results and then divide them by the number of swimmers:

9 + 11 + 9 + 15 + 12 + 9 + 10 = 75

75 ÷ 7 = 10.71428.... which can be rounded up to 11

The median is the middle number in a list of numbers ordered from smallest to largest.

9, 9, 9, 10, 11, 12, 15

so 10 is the median of this set of results.

The range is the difference between the lowest value and the highest value, so the range here is 15 - 9 = 6.
