方法/步骤 1 数据录入 新建Excel文档，录入待分析数据（本例中将数据录入A列，则在后面引用中所有的数据记为A:A）； 2 计算“最大值”、“最小值”、“极差”、“分组数”、“分组组距”，公式如图： 3 分组 “分组”就是确定直方图的横轴坐标起止范围和每个小组的起止位置。选一个比最小值小的一个恰当的值作为第一个组的起始坐标，然后依次加上“分组组距”，直到最后一个数据值比“最大值”大为止。这时的实际分组数量可能与计算的“分组数”有一点正常的差别。类似如下图。 4 统计频率 “频率”就是去统计每个分组中所包含的数据的个数。 最简单的方法就是直接在所有的数据中直接去统计，但当数据量很大的时候，这种方法不但费时，而且容易出错。 一般来说有两种方法来统计每个小组的数据个数：1.采用“FREQUENCY”函数；2.采用“COUNT IF”让后再去相减。 这里介绍的是“FREQUENCY”函数方法： “Date_array”：是选取要统计的数据源，就是选择原始数据的范围； “Bins_array”：是选取直方图分组的数据源，就是选择分组数据的范围； 5 生成“FREQUENCY”函数公式组，步骤如下： 1. 先选中将要统计直方图每个子组中数据数量的区域 6 2. 再按“F2”健，进入到“编辑”状态 7 3. 再同时按住“Ctrl”和“Shift”两个键，再按“回车Enter”键，最后三键同时松开，大功告成！ 8 制作直方图 选中统计好的直方图每个小组的分布个数的数据源（就是“频率”），用“柱形图”来完成直方图： 选中频率列下所有数据（G1:G21),插入→柱形图→二维柱形图 9 修整柱形图 选中柱形图中的“柱子”→右键→设置数据系列格式： 1、系列选项，分类间距设置为0%； 2、边框颜色：实线，白色（你喜欢的就好） 3、关闭“设置数据系列格式”窗口 10 直方图大功造成！ END 制作正态分布图 1 获取正态分布概念密度 正态分布概率密度正态分布函数“NORMDIST”获取。 在这里是以分组边界值为“X”来计算： Mean=AVERAGE(A:A)(数据算术平均） Standard_dev=STDEV(A:A)(数据的标准方差） Cumulative=0(概率密度函数） 2 向下填充 3 在直方图中增加正态分布曲线图 1、在直方图内右键→选择数据→添加→ 2、系列名称：选中H1单元格 3、系列值：选中H2:H21 4、确定、确定 4 修整图形 1、在图表区柱形较下方选中正态分布曲线数据，（正态分布密度值和频率数值相比太小了，实在看不清，多试几次，选中后如图，同时正态分布曲线那数数据处于选中状态）。 5 2、右键→设置数据列格式→系列绘制在→次坐标轴； 关闭，如图 6 更改系列图表类型 1、选中正态分布柱形图→右键→更改系列图表类型 7 2、选中“拆线图” 3、确定 8 平滑正态分布图 选中正态分布曲线→右键→设置数据列格式→线型→勾选“平滑线”→关闭 大功告成！！！ 9 本例中原始数据： 51.7,50.6,57.9,56.9,56.7,56.7,55.3,56.1,53.7,54.5,56.9,51.9,52.1,55.1,54.9,54.7,55.3,55.3,54.5,54.9,54.5,55.3,54.9,54.3,53.7,53.5,53.7,53.1,54.5,53.1,53.9,53.5,53.3,53.9,53.5,53.5,52.5,53.3,53.5,53.3,53.7,53.1,54.5,53.9,56.7,54.5,54.3,55.1,54.1,54.5,53.9,53.1,53.3,55.3,55.7,56.1,54.7,53.1,53.3,52.7,53.1,52.9,53.1,54.3,53.1,52.7,53.1,53.3,53.1,53.3,53.1,53.3,55.1,54.7,54.9,54.3,53.9,53.7,53.9,53.5,54.5,54.3,55.5,55.7,55.5,54.9,55.3,55.5,53.7,54.1,53.9,55.7,55.9,53.7,53.5,53.1,52.3,52.7,52.9,53.3,53.9,52.7,53.5,53.1,52.7,51.9,52.5,53.9,54.5,55.7,55.3,54.9,53.1,52.9,54.1,53.3,54.7,53.9,54.3,54.1,53.7,53.3,52.7,52.9,52.5,53.9,53.5,54.1,54.1,54.7,54.9,54.9,54.1,53.3,52.9,53.7,53.9,54.3,54.1,54.5,54.7,54.9,52.1,52.9,53.5,52.7,53.1,53.1,53.5,52.9,52.9,53.1,53.3,52.7,53.5,53.9,54.9,55.1,54.3,55.1,54.3,54.3,53.9,54.5,54.5,54.3,55.3,54.5,54.9,53.5,52.1,55.3,55.7,55.7,55.5,54.5,57.7,54.7,53.7,53.1,53.7,55.9,56.1,53.9,53.7,53.3,53.9,53.9,54.5,54.7,56.1,55.7,53.1,53.7,53.5,53.9,53.9,53.5,53.3,53.1,52.5,55.9,55.7,54.1,54.3,54.1,54.1,54.5,54.5,55.1,53.1,53.3,54.1,54.3,53.9,54.1,54.7,54.7,53.7,53.1,53.3,52.7,53.5,52.9,53.7,56.5,56.1,55.7,55.5,56.9,57.7,56.5,55.7,54.1,54.7,55.7,55.5,53.1,52.7,53.1,53.3,53.5,54.3,54.1,54.5,54.7,55.7,55.5,54.1,54.3,54.7,53.1,53.3,53.1,52.7,53.1,53.7,53.1,54.7,54.5,55.1,54.7,54.5,56.1,55.7,53.3,52.5,53.7,54.1,53.3,52.1,52.3,53.1,53.3,53.5,53.3,53.1,52.7,53.1,55.7,55.1,54.3,53.7,53.1,52.9,53.1,52.7,52.5,53.1,53.5,53.1,53.3,54.1,55.1,54.9,56.1,55.7,56.5,54.7,53.7

①集中和记录数据，求出其最大值和最小值。数据的数量应在100个以上，在数量不多的情况下，至少也应在50个以上。 我们把分成组的个数称为组数，每一个组的两个端点的差称为组距。 　　②将数据分成若干组，并做好记号。分组的数量在5－12之间较为适宜。　　③计算组距的宽度。用最大值和最小值之差去除组数，求出组距的宽度。　　④计算各组的界限位。各组的界限位可以从第一组开始依次计算，第一组的下界为最小值减去最小测定单位的一半，第一组的上界为其下界值加上组距。第二组的下界限位为第一组的上界限值，第二组的下界限值加上组距，就是第二组的上界限位，依此类推。　　⑤统计各组数据出现频数，作频数分布表。　　⑥作直方图。以组距为底长，以频数为高，作各组的矩形图。
