Kindly tell me what should I change to correct my script?

Write a program that asks the user to enter test scores (1 by 1) using a loop. The number of scores is unknown so keep prompting the user for scores until the user enters -1. We call this the termination condition. Round off all the scores to the nearest integer. Calculate the sum, mean, standard deviation, mode, median, maximum, minimum and range of the scores entered.

MY SCRIPT:

    score= input('Enter test score(enter <0 to quit):'); 
    roundOff = round(score);
    sum=0;
    meanScore= mean(sum)
    stddevScore= std(sum)
    modeScore= mode(sum)
    medianScore= median(sum)
    minScore= min(sum);

    while (score >=0)
        roundOff=round(score)
        score= input('Enter test score(enter <0 to quit):');
        sum=sum + score
        meanScore= mean(sum)
        stddevScore= std(sum)
        modeScore= mode(sum)
        medianScore= median(sum)
        minScore= min(sum)

        score= input('Enter test score(enter <0 to quit):');
    end

• sum is the name of a function. Replace sum by sumScore
• doesn't the code behave as you expect?

Don't use sum, either as a variable or a function. Index the arrays in the loop, for example

medianScores(loopCounter) = score;

At the end of the loop

loopCounter = LoopCOunter + 1;

and of course set it to 1 before the loop starts. Then calculate all the stats after the loop exits, for example:

medianScore = median(medianScores);
