Consider the following set of data Write an mfile that uses

Consider the following set of data. Write an m-file that uses this data to calculate each of the following statistics using \'FOR\' loops: DATA: 92.3 93.2 91.9 93.5 92.7 93.1 93.8 92.4 a. Harmonic mean: H_M=\\frac{n}{1/x_1+1/x_2+...+1/x_n} b. Geometric mean: G_M=\\sqrt[n]{x_1x_2...x_n} c. RMS average: RMS_A=\\sqrt{\\frac{x^2_1+x^2_2...x^2_n}{n}}

Solution

Here is the code for you:

dataSet = [92.3, 93.2, 91.9, 93.5, 92.7, 93.1, 93.8, 92.4];

fprintf(\'Given data set: \');

for i = 1 : length(dataSet)

fprintf(\'%.1f \', dataSet(i));

end

fprintf(\'\ \');

GeometricMean = 1;

for i = 1: length(dataSet)

GeometricMean = GeometricMean * dataSet(i);

end

GeometricMean = GeometricMean ^ (1.0 / length(dataSet));

HarmonicMean = 0.0;

for i = 1 : length(dataSet)

HarmonicMean = HarmonicMean + 1.0 / dataSet(i);

end

HarmonicMean = length(dataSet) / HarmonicMean;

RMS = 0.0;

for i = 1 : length(dataSet)

RMS = RMS + dataSet(i) * dataSet(i);

end

RMS = RMS / length(dataSet);

RMS = sqrt(RMS);

fprintf(\'The harmonic mean of the given data set is: %.1f\ \', HarmonicMean);

fprintf(\'The geometric mean of the given data set is: %.1f\ \', GeometricMean);

fprintf(\'The root mean square of the given data set is: %.1f\ \', RMS);
