Consider the data distribution given in each of the histograms. Assume that the horizontal scales are the same. III IV Which distribution of data has the smallest standard deviation and why? Histogram | because the data values close to the middle are very small. O Histogram II because the distribution of data is roughly uniform. O Histograms III and IV because each data distribution is approximately normal (bell-shaped). Histogram IV because more of the data values are clustered close to the mean
