Histogram question please help?

Question

Three have what seem to me a normal distribution line but the bar are uneven. some are even 3 times more than the other. The bar taper in each nicely and the other looks like two horns and another is zig-zag shape but none on each end. could you still suggest that this is normal but need of more participants? or am i off the mark. Thanks look forward to your reply.

Answer 1

Sorry but you need to express the problem more clearly.

Answer 2

Ihope this will help:

Slants with high numbers on either end is skew, positive or negative

Distributions with two peaks separated by a low area are called bimodal (means two humps, like a camel)

Then of course the normal distribution where the peak is somewhere in the middle.

Only pay attention to the highest scores as comparted to low scores when refrerencing modality (where highest scores lie on the graph).
