Class Average Calculator: For Teachers
You have graded a test, quiz, or assignment. You have a list of student scores. You want to know the class average, the median, the range, and where most students landed.
This calculator does that. Enter each student’s score as a row name, or leave it optional. Hit calculate, and you get the class average plus statistics that show you how the class performed overall: median, min, max, count, and the grade distribution.
What This Calculator Is For
This is a teacher tool for calculating class-wide statistics after grading an assignment or exam.
Each row represents one student’s score. You enter the scores, and the calculator computes:
- Class average: mean percentage
- Median: the middle score when sorted
- Min and max: lowest and highest scores
- Count: number of students
- Letter grade and GPA: for the class average
The result gives you a snapshot of how your class performed. If you’re considering curving grades or adjusting your grading scale, these statistics tell you where the class actually landed versus where you expected them to land.
It is not for students to average their own course grades. That is a different calculator. This is specifically for teachers who need class-level statistics from a set of student scores.
The Three Modes
The calculator has three modes because teachers grade in different ways.
The equal mode default is for when every student’s score counts the same. You enter each student’s percentage, and the calculator computes a simple average. This is the most common use case.
Points mode is for when you are entering raw scores with a maximum possible score. Each student has “earned points” and “possible points,” and the calculator computes the class average percentage from those. Useful if you have not converted to percentages yet.
Weighted mode is unusual but available. You can assign a weight to each student’s score. This is rare in classroom grading you do not usually weight students differently), but it exists if you need it for some specific scenario.
Most teachers will use Equal mode. Enter each student’s percentage in the “Percent (%)” column, hit Calculate, and you are done. The other modes are there if your grading workflow needs them, but Equal handles the vast majority of use cases.
Median, Min, Max: Why They Matter
The class average tells you one thing: the center of mass. But it does not tell you the full picture.
The median is the middle score when you sort all the scores from lowest to highest. If half your class got above 85% and half got below, the median is 85%. The median is less affected by outliers than the mean. If one student scored 20% and everyone else scored 80-95%, the mean might be 78%, but the median might be 88%. The median gives you a better sense of where “most” students landed.
Min and max show the range. A narrow range (e.g., 75%-95%) indicates consistent performance. A wide range (like 40% to 98%) means you have students at very different levels.
The count is just how many scores you entered. Useful sanity check: if you have 30 students but the count shows 28, you missed two.
These statistics together indicate whether the class performed uniformly or showed a large spread.
Considering a Curve
Suppose the class average is significantly lower than you expected. Say, you thought the test was fair for an 80% average, but the class average came out to 62%, you might consider curving.
This calculator does not curve grades for you, but it gives you the data you need to decide whether a curve is warranted. If the median is 60% and the max is 75%, the test might have been harder than intended. If the median is 60% but the maximum is 98%, you have a few students who got it and many who did not; that is a different situation.
The statistics here tell you whether the distribution makes sense for your grading expectations. What you do with that information curve, adjust the scale, re-teach, and re-test is up to you.
Adding and Clearing Rows
The calculator starts with two blank rows, but you can add more.
The “Add 5 rows” button is there because teachers often grade 20-30 students at a time. Clicking it once gets you space for more scores without clicking “add row” 25 times.
The “Clear values” button resets all the scores but keeps the student names if you entered them. Useful if you are reusing the calculator for a second section of the same class or if you want to recalculate with adjusted scores.
The Remove button in each row deletes that student’s score.
FAQ: Class Average Calculator
Is this for students or teachers?
This is a teacher tool. Each row represents a student’s score; the result is the class-wide average and associated statistics. If you are a student trying to average your own course grades, you want a different calculator, that is for averaging YOUR grades across multiple classes, not averaging multiple students’ scores.
Do I need to enter student names?
No. The “Student/label” column is optional. You can leave it blank and enter scores in the Percent (%) column. Names are there if you want to keep track of who got what score, but the calculator does not need them for the math.
What is the difference between the three modes?
Equal mode averages percentages directly. Points mode lets you enter earned/possible points per student and calculates the class percentage from there. Weighted mode lets you assign weights to students (rare). Most teachers use Equal mode, enter each student’s percentage, and calculate.
Does this calculate the median and mode?
Yes. The calculator computes the median score, the mode (most common score, if any), and percentiles. These stats appear in the result card along with the mean class average.
Can I use this for multiple sections of the same class?
Yes, but you would calculate each section separately. Enter Section A’s scores, and get the average. Then use “Clear values” to reset and enter Section B’s scores. The calculator does not combine sections automatically; you would need to do that math yourself if you want an overall average across sections.
Does this calculator curve grades?
No. It gives you the statistics mean, median, min, and max that tell you whether a curve might be warranted, but it does not apply a curve automatically. You would use these statistics to select a curve, then apply it manually.
Class-wide statistics, mean, median, range, and distribution tell you how an assignment or exam went. If the average is where you expected, great. If it is significantly higher or lower, you have data to inform your next move.
This calculator does the math for you. Enter the scores, get the statistics, and you will know how your class performed at a glance.
