What to if modal class is the first class? Thn wht will be the value for preceeding frequency?

[@EnjoyMath]

Yes, this situation can arise...here, the frequency of preceding class will be 0....the reason is that in reality there is no preceding class here only because it's frequency is 0. This point is also mentioned in the video... Pls let me know if you have any questions..

Thank you so much ma’am for your explanation, but what if the highest frequency is repeated twice, what should we do?

[@EnjoyMath]

Thank you so much for the appreciation!! 👍👍👍 When the highest frequency is repeated twice,it means there are 2 values that have the highest frequency i.e. there are 2 mode values..such data is called multi modal data. In such cases, we simply have to take each modal class and apply the mode formula separately to get the 2 mode values... Pls let me know if you have any questions...
