Class mark = (10.5 + 17.5)/2 = 14

Class mark = (10.5 + 17.5)/2 = 14

Class mark = (10.5 + 17.5)/2 = 14

Class mark = (10.5 + 17.5)/2 = 14

The class interval for each interval is the difference between its upper limit and its lower limit.

Step 1: Find the midpoint of each interval. Step 2: Multiply the frequency of each interval by its mid-point. Step 3: Get the sum of all the frequencies (f) and the sum of all the fx. Divide 'sum of fx' by 'sum of f ' to get the mean. Determine the class boundaries by subtracting 0.5 from the lower class limit and by adding 0.5 to the upper class limit. Draw a tally mark next to each class for each value that is contained within that class. Count the tally marks to determine the frequency of each class. What is this? The class interval is the difference between the upper class limit and the lower class limit. For example, the size of the class interval for the first class is 30 – 21 = 9. Similarly, the size of the class interval for the second class is 40 – 31 = 9.

highest value-lowest value/number of classes

Because median is the mid of the class intervals. Therefore, it is a positional measurement. Hence, if the size of class interval increases or decreases then the middle position will also increase or decrease and thus median.

Assuming that you know the population size, N, and that you are confident that the sample size, n, you have chosen is adequate, then the skip interval is ~n/N. For example, if the populaton size if 998 and you reckon that you need a sample size of 20 then the skip interval would be 50.

It will decrease too. * * * * * If it is the confidence interval it will NOT decrease, but will increase.

The width of the confidence interval increases.

In general, the confidence interval (CI) is reduced as the sample size is increased. See related link.

Acceleration has two parts ... its size and its direction.To find the size (magnitude):-- pick a time interval-- measure the speed at the beginning of the interval-- measure the speed at the end of the interval-- subtract the speed at the beginning from the speed at the end-- divide that difference by the length of the time interval-- the result is the magnitude of acceleration during that time interval
