How Do You Travel?
::你旅行怎么样?How could you organize and display the different ways that you and your friends travel to and from school – on foot, by bicycle, by bus, by car, and so on – to find out which method is used by the most students?
::如何组织和展示你和你朋友往返学校的不同方式 — — 步行、自行车、公共汽车、汽车等 — — 找出大多数学生使用的方法?Use the interactive below to compare three types of data displays: Data Table, Bar Chart and Dot Plot .
::使用以下互动方式比较三种类型的数据显示:数据表、条形图和点图。INTERACTIVEHow Do You Travel?-

+Do you want to reset the PLIX?Progress0 / 11.Which type(s) of representation(s) demonstrated in the interactive do you think is best to "organize and display the different ways that you and your friends travel to and from school to find out which method is used by the most students?"
::你认为互动中展示哪类(或几类)代表是否最适合“组织和展示你和你的朋友往返学校以找出大多数学生使用哪种方法的不同方式?”Be sure to answer in sentences, and think through your response before typing it in.
::一定要在句子里回答, 在输入前先考虑一下你的反应。Maximum 1000 characters (1000 Remaining)A frequency table lists items together according to the number of times, or frequency , that the items occur. Here is an example of a frequency table:
::频率表根据项目发生的次数或频率,将项目一起列出。此为频率表的一个示例:Weights of Dogs (kg)
::狗体重(公斤)Interval Frequency 0-9 5 10-19 15 20-29 24 30-39 35 40-49 16 50-59 6 60-69 4 A histogram is a type of frequency plot whose bars represent the frequencies of numeric data within equal intervals (e.g. 1-5, 6-10, 11-15). It also gives a picture of the distribution of a data set by grouping data in intervals. See an example below. Notice that the histogram shows frequencies on the vertical axis and the intervals on the horizontal axis.
::直方图是一种频率图,其条形图代表数字数据在相等间隔内的频率(例如1-5、6-10、11-15),它还通过间距对数据组进行分组来显示数据集的分布情况。见下面的例子。注意直方图显示垂直轴上的频率和水平轴上的间隔。
High School Basketball
::高中篮球The members of the high-school basketball team practice taking free throws. Each player attempts 50 free throws. The number of free throws made by each player is listed below.
::高中篮球队成员免费投球,每个球员尝试50次。下面列出每个球员免费投球的次数。{25, 29, 29, 30, 33, 34, 35, 35, 36, 39, 42, 44}
In this interactive, create a dot plot using the high-school basketball team’s free-throw data above.
::利用高中篮球队的免费发射数据, 建立点图。INTERACTIVENumber of Free Throws MadeDrag the dots to the correct location to create a dot plot using the following data:
::将点拖到正确位置, 以便使用以下数据创建点图 :{25, 29, 29, 30, 33, 34, 35, 35, 36, 39, 42, 44}

Who Let the Dogs Out?!
::谁让狗队出来?A dog walker counts and records the number of dogs at a dog park every morning at 8:00am for several days.
::每天早上8: 00,Here is the data that was collected: { 8, 2, 5, 6, 3, 4, 7, 4, 5, 3, 4, 7, 3, 1, 6, 4, 3, 2, 5, 8}
::以下是所收集的数据:{8,2,5,6,6,3,4,7,4,5,3,4,5,4,3,7,3,3,1,6,4,3,3,3,3,2,5,8}Use this data to answer the questions .
::使用此数据回答问题 。After completing the questions above, click Review Your Answers to see the frequency table you created. Use the frequency table in the following interactive to make a histogram that also represents the data.
::在完成上述问题后,单击“审查您的答复”以查看您创建的频率表。使用以下交互式的频率表来绘制一个直方图,该直方图也代表数据。INTERACTIVENumber of Dogs at a Dog Park Every Morning-
