Online tutors are the people who will help the students in studies and explain the new extra skills by using a step-by-step process. Online tutors are explaining the problems to the students. So the students can clear the doubts within a minute. Statistics is the most important concept in maths. Statistics is the appropriate science. Now we will see the free statistics examples. These examples are given by online tutor.
What is the mean of the following sequence in statistics?
The given numbers are 27,34,48,57,69.
We can find the mean with the help of average.
Mean = `(27+34+48+57+69)/(5)`
Solution is 47.
Find out the Median for the following sequence. 45,48,53,58,67.
First sort the above numbers. We get 45,48,53,58,67.
The center element is 53.
What is the mean, median, mode and range of the below order in statistics?
The given numbers are 26,37,49,57,63,69,78.
Mean is the average of the given number. Calculate average with the help of total value of the given sequence.
Sum of the given numbers are = 26+37+49+57+63+69+78
Total values are divided by 7 (7 is the total numbers) = `(379)/(7)`
Center element of the given series is a median.
The number series is 26,37,49,57,63,69,78.
The center element of the above sequence is 57.
So the median = 57.
Mode is the duplication of the series. The given sequence no duplicates value. Therefore the mode is empty.
Less the low value from the high value of the series.
Homework problem 1
Find the median value for the following series.56,58,63,68,72.
The middle element is 63.
Therefore median =63.
Homework problem 2
Find the mode value for the following.45,48,58,72,80,72.
