2020-2021学年体育学院体育硕士计算机课程大作业¶ 题目一:(30分)¶ 读取iris数据集中鸢尾花的萼片、花瓣长度数据(见已保存的CSV格式文件iris.csv), 并对其: (1)进行排序、去重,并求出和、累积和、均值、标准查、方差、最小值、最大值 (2)绘制Sepal.Length的直方图和密度图 (3)绘制Sepal.Length的分布图 (4)绘制Petal.Length在Species上值的分布,即将三种不同的鸢尾花各自的Petal.Length的分布图画出来 (5)绘制Sepal.Width和Petal.Width的散点图矩阵,以便进行这两种数据特征的对比 数据集说明:¶ Iris数据集是常用的分类实验数据集,由Fisher, 1936收集整理。Iris也称鸢尾花卉数据集,是一类多重变量分析的数据集。 数据集包含150个数据样本,分为3类,每类50个数据,每个数据包含4个属性。可通过花萼长度,花萼宽度,花瓣长度, 花瓣宽度4个属性预测鸢尾花卉属于(Setosa,Versicolour,Virginica)三个种类中的哪一类。 iris以鸢尾花的特征作为数据来源,常用在分类操作中。该数据集由3种不同类型的鸢尾花的各50个样本数据构成。 其中的一个种类与另外两个种类是线性可分离的,后两个种类是非线性可分离的。 该数据集包含了4个属性: & Sepal.Length(花萼长度),单位是cm; & Sepal.Width(花萼宽度),单位是cm; & Petal.Length(花瓣长度),单位是cm; & Petal.Width(花瓣宽度),单位是cm; & Spiece(种类):Iris Setosa(山鸢尾)、Iris Versicolour(杂色鸢尾),以及Iris Virginica(维吉尼亚鸢尾)。 数据类型对象 (dtype)¶ 数据类型对象(numpy.dtype 类的实例)用来描述与数组对应的内存区域是如何使用,它描述了数据的以下几个方面:: 数据的类型(整数,浮点数或者 Python 对象) 数据的大小(例如, 整数使用多少个字节存储) 数据的字节顺序(小端法或大端法) 在结构化类型的情况下,字段的名称、每个字段的数据类型和每个字段所取的内存块的部分 如果数据类型是子数组,那么它的形状和数据类型是什么。 字节顺序是通过对数据类型预先设定 < 或 > 来决定的。 < 意味着小端法(最小值存储在最小的地址,即低位组放在最前面)。> 意味着大端法(最重要的字节存储在最小的地址,即高位组放在最前面)。 dtype 对象是使用以下语法构造的: numpy.dtype(object, align, copy) […]
