In the figure data is:
S, A, H, S, A, M, S, T, M, T, H, % A, T, S, M, H, M, A, S, T, M, A, T, S, T, H, M.
By arranging the letters, of same type together.
A, A, A, A, A, H, H, H, H, M, M, M, M/M, M, S, S, S, S, S, S, T, T, T, T, T, T, T.
As T occurs most frequently in the data.
∴ Mode = T Data having only one mode is known as unimodal data.
So, given data is unimodal data.
