see the highest frequency. see the X value for that. then apply the formula mode =l+(f-f1) /(f-f1-f2) x c
l = the lower limit. eg : 20 -30 the lower limit is 20
f is the highest frequency
f1 is the frequency above highest frequency
f2 is the frequency below highest frequency.
c is higher limit - lower limit. eg : 30-20 =10.
therefore c = 10.
l = the lower limit. eg : 20 -30 the lower limit is 20
f is the highest frequency
f1 is the frequency above highest frequency
f2 is the frequency below highest frequency.
c is higher limit - lower limit. eg : 30-20 =10.
therefore c = 10.
