Haze| SG hi i am facing a problem which i dunno how to solve... pls help me.... The annual salaries (in thousands of dollars) for all the staff at LCK company are as below: $'000 frequency 20 to 29 4 30 to 29 8 40 to 49 4 50 to 59 8 60 to 69 3 Question is : Find the modes for the above data Thanks !
Haze| SG sorie.. but answer is wrong.. there should be 2 modes in this set of data i just don't understand how to get these 2 modes.
crushedhearts SG coolmyth is right. mean = find average median = the "middle one" mode = highest frequency one
ndmmxiaomayi SG Based on what you give, CoolMyth's answer is correct as finding mode means finding the one which has the highest frequency.
Haze| SG i am sorry but the answers are wrong the same type of question came out in every year's exams so i am desperate to find the answer. Qn is: $'000 frequency 20 to 29 4 30 to 39 8 40 to 49 4 50 to 59 8 60 to 69 3 the answer is : 29.5 + (4/(4+4)(10) = 34.5 49.5 + (4/(4+3)(10) = 55.214
Haze| SG because i do not understand the answer at all the answer is i copied from the answer sheet i want to know why the answer is like this. but anyway thanks everyone it's too late i am having my exams in another 30 mins
Haze| SG in this case, it is correct. because there are 2 questions asked in the same way. both answers are in this manner. and both came out in the past year exam papers. anyway i kena liao the exam paper got this qn lost 8 points. god
