Produce random number using normal distribution

I have a csv File that looks like :
subjects,       WeightedAverage,     WeightedStandardDev,    NumberofExams,
MathMark,              1.5,                 0.2,                   5,
PhysicMark,            1.6,                 0.4,                  10,
EnglishMark,            3,                  1.2,                  8,
PhiloMark,             8.2,                 1.5,                  9,
Others                 9.2,                 3.2,                  5,

I have another file where I need to generate data this way for each subject above :

For example for the subject MathMark the corresponding table should be :

 
NumberofExams                                     Mark                                                                              1                         =NORMINV(RAND(),WeightedAverage=1.5,WeightedStandardDev=0.2)
2                         =NORMINV(RAND(),WeightedAverage=1.5,WeightedStandardDev=0.2)
3                         =NORMINV(RAND(),WeightedAverage=1.5,WeightedStandardDev=0.2)
4                         =NORMINV(RAND(),WeightedAverage=1.5,WeightedStandardDev=0.2)
5                         =NORMINV(RAND(),WeightedAverage=1.5,WeightedStandardDev=0.2)

Open in new window


For example for the subject EnglishMark the corresponding table should be :

 
NumberofExams                                   Mark                                                                                            
1                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)                                                2                           =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)                                              3                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)                               
4                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)                                  
5                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)             
6                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)   
7                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)
8                          =NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)

I'm sorry but I don't follow your presentation of the problem or the objective.
It appears to be Excel but it isn't.   Perhaps it's just a bit too terse.

For example:
What is this?:
=NORMINV(RAND(),WeightedAverage=3,WeightedStandardDev=1.2)  
It's not an Excel formula or even a set of them separated by commas.
So, what is it?  A specification?  Pretty slim specification.....

@Fred Marshall YEAH IT S just a specification not a correct a formula , a way to generate a random value depending on a normal distribution of a couple of <average,stdev> that should be extracted from other file (csv)
@Martin Liss  how can I add this macro using excel 2010 ?
In Excel, Press Alt+F11 to open the Visual Basic Editor (VBE)

Right-click on your workbook name in the "Project-VBAProject" pane (at the top left corner of the editor window). If you don’t see an existing module then select Insert -> Module from the context menu. Otherwise just select the module.

Copy the macro (you can use the ‘Select All’ button if you like) and paste it into the right-hand pane of the VBA editor ("Module1" window)

Press Alt+F11 again to go back to Excel

Optionally, press Alt+F8 to open the "Macro" dialog window. Select the macro, click ‘Options…’,  hold down the Shift key and type the letter A (or any other letter) and click ‘OK’. Then anytime you want to run the macro press Ctrl+Shift+A.

When you close the workbook you will need to save it as an xlsm or xls file if it’s not already one of those.
