Question

solve it using MATLAB and include all steps please

The vector G = [68, 83, 61, 70, 75, 82, 57, 5, 76, 85, 62, 71, 96, 78, 76, 68, 72, 75, 83, 93] represents the distribution of final grades in a dynamics course. Compute the mean, median, mode, and standard deviation of G. Which better represents the "most typical grade, " the mean, median, or mode? Why? Use MATLAB registered sign to determine the number of grades in the array (don't just count them) and to sort them into ascending order.

Answer 1

Please give the thumbs up, if it is helpful for you!!. Let me know if you have any doubts.

G=[68,83,61,70,75,82,57,5,76,85,62,71,96,78,76,68,72,75,83,93];

%mean
vec_mean = mean(G)

%median
vec_median=median(G)

%mode
vec_mode= mode(G)

%standard deviation
standard_deviation= std(G)

%number of grades
vec_length = length(G)

%sort
A=sort(G);

A

The median represent the 'most typical grade' because the  mean is lower than most of the scores in the vector.

Output:
