requesting formulas for datapoints and percentages

I do not understand formulas and the help menu is confusing to me. I am asking for the formulas for the following.


I have a sheet with the following data.

The first column is M=boys, F=girls

The second column is grade

The following columns are points scored by the individual. The total points are in the bottom footer.


I would like to calculate the following automatically (I am presently doing it by hand).

Section 1

Total number and percentage of all participants.

Total number and percentage of boys participants.

Total number and percentage of girls participants.

Total number and percentage of each grade participants.

Section 2

Boys points and percentage of total points.

Girls points and percentage of total points.

Each grades points and percentage of total points.

Upperclassmen points (grades 11 and 12 combined) and percentage of total points.

Underclassmen points (grades 9 and 10 combined) and percentage of total points.


I assume this can be added in another spreadsheet below this one. Any help with this is appreciated. I might be able to figure it out if someone were to supply one in each section. Thank you

I'm not sure if your last two columns are both representing scores. In any case, you can achieve what you're aiming for using some simple formulas like SUMIF, COUNTIF, and COUNTA.


I've randomly selected a few rows of data from your image and created four tables below: participant statistics by gender, participant statistics by grade, score statistics by gender, and score statistics by grade.


In Participants (gender), the main formulas used are COUNTA and COUNTIF. COUNTA counts the number of non-empty cells in a range, which is used to calculate the total number of participants. COUNTIF counts the number of cells that meet a certain condition, which is used to count the gender.


B12: =COUNTIF($A$2:$A$7,"F")

B13: =COUNTIF($A$2:$A$7,"M")

B14: =COUNTA($A$2:$A$7)


The formulas in C12 to C14 are simple division formulas.


In Participants (grade), the same two functions mentioned earlier are used, but the formulas are written slightly differently.


B18: =COUNTIF($B$2:$B$7,"9")

B19: =COUNTIF($B$2:$B$7,"10")

B20: =COUNTIF($B$2:$B$7,"11")

B21: =COUNTIF($B$2:$B$7,"12")

B22: =COUNTA($A$2:$A$7)


The formulas in C18 to C22 are simple division formulas.


In Score (gender), the SUM and SUMIF formulas are needed. SUM calculates the total of a fixed range of cells, while SUMIF sums the cells in a range that meet a specific condition.


F12: =SUMIF($A$2:$A$7,"F",$C$2:$C$7)+SUMIF($A$2:$A$7,"F",$D$2:$D$7)

F13: =SUMIF($A$2:$A$7,"M",$C$2:$C$7)+SUMIF($A$2:$A$7,"M",$D$2:$D$7)

F14: =SUM(C2:C7,D2:D7)


The formulas in G12 to G14 are simple division formulas.


In Score (grade), the same two functions mentioned earlier are used, but the formulas are written slightly differently.


F18: =SUMIF($B$2:$B$7,"9",$C$2:$C$7)+SUMIF($B$2:$B$7,"9",$D$2:$D$7)

F19: =SUMIF($B$2:$B$7,"10",$C$2:$C$7)+SUMIF($B$2:$B$7,"10",$D$2:$D$7)

F20: =SUMIF($B$2:$B$7,"11",$C$2:$C$7)+SUMIF($B$2:$B$7,"11",$D$2:$D$7)

F21: =SUMIF($B$2:$B$7,"12",$C$2:$C$7)+SUMIF($B$2:$B$7,"12",$D$2:$D$7)

F22: =SUM(C2:C7,D2:D7)


The formulas in G18 to G22 are simple division formulas.


In columns H and I, you can merge the two adjacent cells and then use the SUM formula along with a simple division formula to combine and calculate the statistical data for 9th-10th grade and 11th-12th grade students.

> Is there a way to use the COUNTIF twice in a formula?


You use COUNTIFS()


COUNTIFS() works like COUNTIF(), except there are multiple ranges that are checked, and only cells that match all checks are summed.


For example, if Column A contains Gender, and Column D contains the score, then:


=COUNTIFS($A,"M", $D,"")


will tell you how many blank cells there are in column D that match rows with an 'M' in column A


Or, to count how many valid (non-blank) male scores:


=COUNTIF($A,"M") - COUNTIFS($A,"M", $D,"")


Where COUNTIF($A,"M") tells you how many Males, from which you subtract the number of blank scores.

For this kind of analysis, I highly recommend taking a look a Pivot Tables. They are easy to use.


For example, in five minutes, with no formulas, just clicks and drags, I produced the following three tables:




To create a Pivot Table click in the table with the data and from the menu choose Organize > Create Pivot Table > On Current Sheet.


Then in the Pivot Options pane at the right drag tokens down into to the boxes below. Create multiple Pivot Tables based on the same data table. Try different things. Click the circled i's to see what is behind them. Your original data will not be disturbed.


Create a pivot table in Numbers on Mac - Apple Support

Intro to pivot tables in Numbers on Mac - Apple Support


and more at Help > Numbers Help in your menu.


There is also a Pivot Table Basics template at File > New in the menu.


If you need to show the results to others then you may not succeed at getting exactly the right look. In that case just copy-paste Pivot Table results into a "regular" Numbers table and format as desired.


If you change or add data to your original table on which the Pivot Tables are based, you can update each Pivot Table by clicking it and from the menu choosing Organize > Refresh Pivot Table.

This helps and have half of what I need. Thank you.


Part II.


Is there a way to use the COUNTIF twice in a formula? Say there are a total of 10 males (or 9, 10, 11, 12th graders) but only 8 score. I want to be able to track how many score and the percentage of that group's total. The part I am stumbling on is how do I count the quantity of scorers, not how many points, knowing blanks are not the same as zero points.


An entry of any type means they participated. A blank means they did not participate.
