    ::[图1]

    Sue collected  data  over an entire year to show how many vegetables she grew. 
    ::Sue收集了整整一年的数据,以显示她种植了多少蔬菜。

    Total vegetables = 400
    ::蔬菜共计=400

    Carrots = 120
    ::胡萝卜=120

    Potatoes = 40
    ::土豆=40

    Tomatoes = 80
    ::番茄=80

    Zucchini = 60
    ::Zucchini = 60

    Squash = 100
    ::Squash = 100

    She displays it in a  circle graph  to visually see which vegetables grew best in her garden and which vegetables grew the least.
    ::她用圆形图显示,以观察哪些蔬菜在她的花园中生长最好,哪些蔬菜种植最少。

    Sue can now  analyze  the circle graph to draw conclusions based on her data. She wants to  rank  her vegetables from least amount grown to most grown.
    ::Sue现在可以分析圆形图,以便根据她的数据得出结论。她想将她的蔬菜从最少种植到最多种植。

    In this concept, you will learn how to read circle graphs to answer questions. 
    ::在此概念中,您将学习如何阅读圆形图解答问题。

    Circle Graphs
    ::圆形图

    Like bar graphs, line graphs, and other data displays,  circle graphs  are a visual representation of data.
    ::象条形图、线形图和其他数据显示,圆形图是数据的直观表示。

    In particular, a circle graphs are used to show the relationships between a whole and its parts. The whole might be a total number of people or items. It can also be  decimals  that add up to 1. Decimals are related to  percentages , they are both parts of a whole. A circle graph will often show percents that add up to 100  percent .
    ::特别是,使用圆形图来显示整体及其部分之间的关系。 整个图中可能包含人或项目的总数。 也可能是小数数组, 相加到 1 。 十进制与百分比有关, 它们都是整体的一部分。 圆形图中往往显示百分率, 共加到100% 。

    Take a look at the circle graph below. It shows which pets the students in the sixth grade have.
    ::看看下面的圆形图,它显示了六年级学生的宠物。

    lesson content

    In order to interpret circle graphs, you first need to understand what “whole” and “parts” it represents. This information can be found in the graph’s title and labels of the parts.
    ::为了解释圆形图,您首先需要理解它代表的“ 整体” 和“ 部分 ” 。 此信息可以在图的标题和部分的标签中找到 。

    Each section is labeled according to a percentage. Each percentage is a part of a whole. The whole is the whole class or 100% of the students. The largest group would have the greatest percentage. In this case, dogs are the most popular pet with 40% of the kids in the sixth grade having dogs. The smallest group would have the smallest percentage. In this case, there are two groups that are the smallest or the least popular pet. In this circle graph, rabbits and birds are the smallest group. Since this is a graph about popularity, you can say that the least popular pets are rabbits and birds. The most popular pet is a dog.
    ::每个部分都按百分比进行标签。 每一百分比都是整体的一部分。 整体是整个班级或100%的学生, 最大群体将拥有最大比例。 在这种情况下, 狗是最受欢迎的宠物, 40%的六年级儿童有狗; 最小群体将拥有最小比例。 在这种情况下, 有两个群体是最小或最不受欢迎的宠物。 在这个圆形图中, 兔子和鸟类是最小群体。 由于这是关于受欢迎程度的图表, 您可以说最不受欢迎的宠物是兔子和鸟类。 最受欢迎的宠物是一只狗。

    Here is another example:
    ::以下是另一个例子:

    Circle graphs display data so that you can make generalizations about different components of the data. Circle graphs are also used to make predictions.
    ::圆形图显示数据,以便您能够对数据的不同组成部分进行概括化。圆形图也用于预测。

    This information can help to understand the  likelihood  that other people will choose the same categories based on the percentages that are greatest and least. Suppose, for instance, that a student was absent from the class when the  poll  was taken to see which kind of movie the students preferred. Which category would the absent student most likely choose based on the data shown in the graph?
    ::这种信息可以帮助理解其他人根据最大和最小的百分比选择相同类别的可能性。 比如,在进行民意调查以查看学生喜欢哪类电影时,学生缺席了班级。 缺席学生最有可能根据图表中的数据选择哪类?

    Because most of the students selected comedy as their favorite type of movie, it would be more likely that the absent student would also choose comedy. That is not a certain answer, just a prediction. Remember, a prediction is made based on an assumption or pattern but it is not an exact answer.
    ::因为大多数学生选择喜剧作为他们最喜欢的电影类型,所以缺席学生也更有可能选择喜剧。 这不是一个特定答案,而只是预测。 记住,预测是基于假设或模式做出的,但不是准确答案。

    Examples
    ::实例

    Example 1
    ::例1

    Earlier, you were given a problem about Sue and her vegetable garden.
    ::早些时候,你得到一个问题 关于苏和她的菜园。

    This is the data that Sue has collected over an entire year of growth in her garden:
    ::这是苏在她花园生长的整整一年里收集的数据:

    Total vegetables = 400
    ::蔬菜共计=400

    Squash = 100
    ::Squash = 100

    Zucchini = 60
    ::Zucchini = 60

    Potatoes = 40
    ::土豆=40

    Carrots = 120
    ::胡萝卜=120

    Tomatoes = 80
    ::番茄=80

    Sue created a circle graph to display her data visually.
    ::Sue创建了一个圆形图,以直观显示她的数据。

    Now, Sue wants to rank her vegetables from least amount grown to greatest amount grown. In order to do this, she needs to read and interpret her circle graph.
    ::现在,苏希望将蔬菜从最小数量种植到最大数量种植。为了做到这一点,她需要阅读和解读她的圆形图。

    First, Sue will rank the percentages of each vegetable from least to greatest. This gives her a start on ranking them correctly.
    ::首先, Sue 将把每种蔬菜的百分比从最小排到最高。 这样她就可以开始正确排在位次上。

    10%

    15%

    20%

    25%

    30%

    Next, Sue matches up each percentage with the color that percentage represents.
    ::接下来,Sue将每一百分比与该百分比所代表的颜色相匹配。

    10% Light Blue
    ::10% 浅蓝色

    15% Green
    ::15% 绿

    20% Red
    ::20% 红

    25% Purple
    ::紫 25% 紫

    30% Blue
    ::30% 蓝色

    Then, Sue uses her key to match the sections in the circle graph with each of the vegetables in her garden. This will display her rank of least amount grown to greatest amount grown.
    ::然后,Sue用她的钥匙把圆形图中的各个部分 和花园里的每一种蔬菜匹配起来。这将显示她的军衔 最少,增长最多。

    10% Light Blue- Potatoes
    ::10% 浅蓝色土豆

    15% Green- Zucchini
    ::15% 绿色-Zucchini

    20% Red- Tomatoes
    ::20%红番茄

    25% Purple- Squash
    ::25% 紫-斯夸斯

    30% Blue- Carrots
    ::30% 蓝胡萝卜

    The answer is from least to greatest amount grown: Potatoes, Zucchini, Tomatoes, Squash, Carrots. 
    ::答案从最少到最大的增长是:土豆、Zucchini、番茄、Squash、胡萝卜。

    Sue can also conclude that Potatoes grew the least in her garden which Carrots grew the most.
    ::Sue也可以得出这样的结论:土豆在她的花园中生长最少,胡萝卜生长最多。

    ::下一步, 查找该节旁边的百分率, 以确保它是图中代表的最大百分率。 此节代表55%, 这是图中最大的一节 。

    Then, look at the key to determine which activity is represented by the 55% blue section. The blue section represents sports.
