for mean find the xi first and multiply it by fi to get fixi then put the formula that is mean=fixi/fi
for mode just find the f1 f2 and f0 and lower limit and h and then put the formula mode = l+(f1 - f0/ 2f1 -f0- f2)*h
in median just find the cf and n and put the formula
median=l+(n/2-cf/f)*h
for mode just find the f1 f2 and f0 and lower limit and h and then put the formula mode = l+(f1 - f0/ 2f1 -f0- f2)*h
