I. blank

Name: Sort() Parameter(s): float[] : data int : size Return: nothing Description: sorts the elements of data whose size is size in ascending order.

II. blank

Name: Maximum() Parameter(s): float[] : data int : size Return: float Description: returns the largest element of data whose size is size.

III. blank

Name: Minimum() Parameter(s): float[] : data int : size Return: float Description: returns the smallest element of data whose size is size.

IV. blank

Name: Range() Parameter(s): float[] : data int : size Return: float Description: returns the distance between the smallest and largest elements of data whose

size is size.

V. blank

Name: Median() Parameter(s): float[] : data int : size Return: float Description: returns the median of elements of data whose size is size. If an ordered list has an odd number of elements, the median is the middle number; otherwise, it is the average of the two middle numbers.

VI. blank

Name: Mean() Parameter(s): float[] : data int : size Return: float Description: returns the average of elements of data whose size is size.

VII. blank

Name: StandardDeviation() Parameter(s): float[] : data int : size Return: float Description: returns the standard deviation of elements of data whose size is size.

VIII. blank

Name: OutlinerCount() Parameter(s): float[] : data int : size Return: float Description: returns the number of elements of data whose size is size that are outliners. An outliner is a values whose z-score is either less than -2 or greater than 2.

This is what I have with my current code.

I'm having trouble finishing the code. This is what I have so far. The Repository and the main shouldn't be altered.

StandardDeviation.h:

#ifndef STANDARDDEVIATION_H #define STANDARDDEVIATION_H #include "Archive.h" #include  namespace labI { float StandardDeviation(float data[], int size) { return -1; } } #endif 

main.cpp:

#include "Repository.h" using namespace labI; void TestUnits() { bool (*func[8])() = { &SortTest, &MinimumTest, &MaximumTest, &RangeTest, &MedianTest, &MeanTest, &StandardDeviationTest, &OutlinerTest }; string tests[8] = { "Sort ", "Minimum ", "Maximum ","Range ", "Median ", "Mean ", "Standard Deviation ", "Outliner Count " }; for (int i = 0; i < 8; i += 1) { cout << tests[i] << ((func[i]()) ? ("Test has passed.") : ("Test has failed.")) << " "; } } int main() { float data[30][17]; if (RetrieveData(data, "data.dat")) { TestUnits(); PrintReport(data, 30, "records.dat"); } else { cout << "Could not retrieve data. "; } return 0; }
