By the end of this lesson you will be able to explain/calculate the following: 1. Mean for data in frequency table 2. Mode for data in frequency table
2
Score (x) Frequency (f) ( f x x ) 1 2 3 4 5 When data are presented in a frequency distribution table
3
Score (x) Frequency (f) ( f x x ) 13 20 37 48 54 When data are presented in a frequency distribution table
4
Score (x) Frequency (f) ( f x x ) 133 200 3721 4832 5420 When data are presented in a frequency distribution table
5
Score (x) Frequency (f) ( f x x ) 133 200 3721 4832 5420 ∑(f) = 22 ∑( ( f x x ) = 76 When data are presented in a frequency distribution table
