//by bell /* List Statistics challenge by John Wells Generate N random numbers between one & nine and calculate the mean, median, & mode. Implement an insertion sort as part of your main loop or recursion. The frequency data processing for the mode is the only other loop or recursion allowed. Your code should read N from the console, when user specified, and default to 50, when not specified. It should work correctly for one to 500 numbers. Your code must not use any built in or library provided features beyond an ordered list of elements and a random number generator. You must physically code the sort and statistics calculations yourself. During that sort, generate each number, display the original numbers, total their count & sum to calculate the mean plus terminate the loop, store them in sorted order within the list so the median can be found, and store a tuple of value & frequency in a second sorted list to calculate the mode. Calculate mean as sum(x/n) Calculate variance as (1/n * sum x**2)-mean**2 */ #include #include #include using namespace std; int main() { int n=50,k,mode=-1,modecount=-1,median=0,me=0; vector v(9,0); srand(time(NULL)); cout<<"Input how many numbers, from 1 to 500?"<>n; double dn=double(n), mean=0,var=0,a; cout<<"The "<modecount){ mode=k+1; modecount=v[k]; } a=double(k+1)/dn; mean+=a; a*=(k+1); var+=a; } cout<n){ cout<<" MEDIAN "; median=-n; me=((me)?(me+i+1):(2*i+2)); } if((2*median)==n){ cout<<" MEDIAN "; me=i+1; if((n%2))median=-n; } } cout<9)?"s are ":" is "); do{ cout<1); cout<<"occurring "<
