subject: Operating System Statistics [print this page]

Introduction to operating system statistics:

Statistics is the process of learning about the mean, mode, median and also range. The statistics have the procedure for the design of the survey and also the experiments. Statistics has the collection, analysis and also the interpretation. Statistics is also used for finding the population analysis. Statistics determines the collection, analysis of the data. The operating system is the software which runs in the computer machine that manages the computer hardware and the software. This article contains the details about the operating system statistics.

Examples for Operating System Statistics:

Example 1 for operating system statistics:

What is the mean, mode and also the median for the set of data 143, 147, 143, 148, 145?

Solution:

The given set of data is 143, 147, 143, 148, 145.

The formula for estimate mean = '(x_1+x_2+x_3+. . . . . .+x_m)/m'

Step 1: Mean = '(143+147+143+148+145)/5'

Step 2: Mean =' 726/5'

Step 3: Mean = 145.2

Step 4: 143, 143, 145, 147, 148. (Ascending order)

Step 5: Median = 145

Step 6: Mode = 143 (Repeated data)

The mean value for the set of data 143, 147, 143, 148, 145 is 145.2. The median for the given set of data is 145 and mode is 143.

Example 2 for operating system statistics:

Find the mean, mode and also the median for the data 155, 159, 156, 159, 153.

Solution:

The given set of data is 155, 159, 156, 159, 153.

The formula for estimate mean = '(x_1+x_2+x_3+. . . . . .+x_m)/m'

Step 1: Mean = '(155+159+156+159+153)/5'

Step 2: Mean = '782/5'

Step 3: Mean = 156.4

Step 4: 153, 155, 156, 159, 159. (Ascending order)

Step 5: Median = 156

Step 6: Mode = 159 (Repeated data)

The mean value for the set of data 155, 159, 156, 159, 153 is 156.4. The median for the given set of data is 156 and the mode is 159.

Example 3 for operating system statistics:

Find the mean, mode and also the median for data 296, 292, 293, 295, 292, 299.

Solution:

The given set of data is 296, 292, 293, 295, 292, 299.

The formula for estimate mean = '(x_1+x_2+x_3+. . . . . .+x_m)/m'

Step 1: Mean = '(296+292+293+295+292+299)/6'

Step 2: Mean = '1767/6'

Step 3: Mean = 294.5

Step 4: 292, 292, 293, 295, 296, 299. (Data in ascending order)

Step 5: Median = '(293+295)/2 ' = 294

Step 6: Mode = 292 (Repeated data)

The mean for the set of data 296, 292, 293, 295, 292, 299 is 294.5. The median for the given set of data is 94 and the mode is 292.

Practice Problem for the Operating System Statistics:

Find the mean, mode and also median for the data 81, 86, 83, 85, 86.

Answer: mean = 84.2, median = 85, mode = 86.

Find the mean, mode and median for the data 59, 54, 50, 55, 58, 53, 57, 53.

Answer: mean = 54.8, median = 54.5, mode = 53.
