as i understand peak is maximum value .. and 20 , 21 are the maximum . .

so those are peaks

Oh yar we are still not able to decide .

Hi;

I drew arrows to the peaks in post #20.

To decide you need the data.

hy no .. . How did say that its peak . We can see it graphically ,

but i still do't understand how can say its out peak .

Do you have the data values? That is how you determine it.

Count up each type of data value the way I did in post #4. That is how you get those peaks and valleys. You do not need the histogram.

Oh u are making me confuse . leave it . now .

I need to work with histogram .

The histogram is for the eye to get an idea what the data looks like. The data itself is the best thing.

Look at post #4, the data.

There

4 ones

1 two

1 three

3 fours

you do the rest. You will see there are more ones than anything else. That is a peak.

Of course that result can be rigorously obtained, but who cares?

ok but i am asking about probability .

How can we compute probability of each bin ?

Also how can we compute Bayesian formula in histogram post #1 .

As Bayesian formula can show that posterior probability is proportional to density value .

Hi;

Just take how many is in that bin and divide it by the total number.

Of course that result can be rigorously obtained, but who cares?

and how about Bayesian formula in histogram post@1 .

As Bayesian formula can show that posterior probability is proportional to density value .

That's y i am interested in Bayesian formula .

Hi tina123;

I do not understand either term. You will have to explain to me what they mean.

Of course that result can be rigorously obtained, but who cares?

Hi;

I am sorry but I can not apply Bayes theorem here. What question is being asked? I do not know. Hard enough to solve a problem but having to guess at what it is, is too tough.

Please go here so you can ask a specific problem:
