MyLab Statistics (MLS) Grade Example
MLS grade calculation is based on the Weighted Average method.
Each section has equal weights.
This is how your MLS grades are calculated.
(1.) The MyLab Statistics (MLS) has 4 chapters: Chapters 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.
(2.) The 10 chapters has 31 main sections.
These are Sections: 1.1, 1.2, 1.3, 2.1, 2.2, 2.3, 2.4, 3.1, 3.2, 3.3, 4.1, 4.2, 4.3, 5.1, 5.2, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 7.1, 7.2, 8.1, 8.2, 8.3, 9.2, 9.3, 10.1, 10.2, 10.3
Because I do not want to overwhelm you with many questions per section, each section is further divided into
more sections.
Hence, the 31 sections are further divided into 44 sections.
So, we are dealing with 44 sections. Please see them in the calculator.
(3.) 44 sections count for 100% on MLS
This implies that each section count for
$
\dfrac{100}{44} = 2.272727273\% \\[5ex]
$
This is what should be entered in the Weight section of the calculator.
(4.) Let us do an example.
Assume Student A made a:
98% on Section 1.1-1st
90% on Section 1.1-2nd
86% on Section 1.2
Student A is aware that 100% can be made on all three sections by doing similar questions of the questions got incorrectly.
However, Student A is content with the grades made so far and wants to find the current grade.
What is the current grade for Student A?
| MLS Section | Weight (%) | Your Score (%) | Weighted Score (Weight * Your Score) |
|---|---|---|---|
| Section 1.1-1st | 2.272727273 | 98 | 222.7272727 |
| Section 1.1-2nd | 2.272727273 | 90 | 204.5454545 |
| Section 1.2 | 2.272727273 | 86 | 195.4545455 |
| $\Sigma Weights = 6.818181818$ | $\Sigma Weighted\;\;Scores = 622.7272727$ | ||
| $ Current\;\;Grade = \dfrac{\Sigma Weighted\;\;Scores}{\Sigma Weights} = \dfrac{622.7272727}{6.818181818} = 91.33333333 \approx 91\% $ | |||
Student A's current MLS grade based on these three sections is 91%.
This is the grade that the student will see in the MLS gradebook.
