18.93 is Modal of Group A  & 18.83 is Modal of Group B

Step-by-step explanation:

                        GROUP A              GROUP B

Class               f                                f              

16 - 18              50                           54        

18 - 20             78                           89        

20 - 22            46                           40          

22 - 24            28                           25        

24 - 26            23                            17          

Modal of group A  =  18  +  2 * ( 78 - 50) /(78 - 50 + 78  - 46)

= 18  + 2 * 28/(60)

= 18 + 0.93

= 18.93

Modal of group B =  18  +  2 * ( 89 - 54) /(89 - 54 + 89  - 40)

= 18  + 2 * 35/(84)

= 18 + 0.83

= 18.83
