WebbWith the Histogram tool, you can examine the shape of the distribution by direct observation. By reviewing the mean and median statistics, you can determine the center location of the distribution. Notice that in the figure below the distribution is bell-shaped, and since the mean and median values are very close, this distribution is close to normal. WebbA histogram works best when the sample size is at least 20. If the sample size is too small, each bar on the histogram may not contain enough data points to accurately show the distribution of the data. The larger the sample, the more the histogram will resemble the shape of the population distribution. A histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson. To construct a histogram, the first step is to "bin" (or "bucket") the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval. The bins are usually specified as consecutive, non-overlappi… small sofa sectional sleeper
