Introduction to Statistics Midterm Exam Help:

Statistics means that the formal science. Those are generating help with the effective use of mathematical terms. In this statistics we are learning about the concepts like mode, median, mean and range. They should be help with interpretation and analysis of the terms. Here we are going to see help with problems for statistics midterm exam.

 

 

Problems for Statistics Midterm Exam:

 

The following questions are the midterm exam questions.

Question 1:

What is the mean of the following numbers, 90,16,27,34,55,81?

Question 2:

What is the mode for the following group of numerical number series, 77,49,16,30,28,21,16?

Question 3:

Find out the range of the following series, 68,91,55,30,27,36.

Question 4:

Question 6:

Find out the range of the following series, 36,24,19,80,77,51.

These are the questions that are help with midterm exam.

 

Solutions for Statistics Midterm Exam:

 

These are the solutions for the midterm exam questions.

Solution 1:

Average of the given series is known as the mean. The mean is, `(90+16+27+34+55+81)/(6)` = `(303)/(6)` = 50.5

     So the solution should be 50.5.

Solution 2:

The mode value of the group of numbers should be a number which should happen most frequently in the given list. The given series 16 is takes place in 2 times. So the value of mode is 16.

Solution 3:

Subtract the smallest value from the highest value is known as the range. Here the range is 91-27=64.

Solution 4:

The central value of the given series is known as the median of the series. For calculating median we need to arrange the numbers in an order. So the arranged values are 22,44,47,50,97. Therefore solution is 47. 

Solution 5:

The mode value of the group of numbers should be a number which should happen most frequently in the given list. The given series 40 is takes place in 2 times. So the value of mode is 40.

Solution 6:

Subtract the smallest value from the highest value is known as the range. The given series range value is 80–19=61.

That’s all about the statistics midterm exam help.
