why are error bars smaller in a histogram which model will have the best histogram if it uses least squares can i use chi squares when fitting pixel chi squares what makes histograms good why would histograms be bigger than normal why do chi squares get larger what is the difference between histogram and poisson why do you need chi squared in histograms why are standard deviations smaller than variance how do you calculate the range of error bars in the histogram of the data what is normal standard deviation and chi squared variance why would histograms be smaller? why is the standard deviation of a histogram higher than the variance of the normal histogram? why should standard deviation be larger what is the normal deviation in a histogram why is a histogram histogram too small what is the standard deviation compared to the histogram how to calculate chi square error of histogram in computer when a model is binned does the variance of the data have to be the same as the standard deviation of the sample is histogram histogram chi squared
