Types of Patterns
::类型类型In addition to linear patterns, discussed in , there are many other types of patterns, and in many cases, there is no pattern at all. If the four tests below are performed, which study would most likely result in a linear pattern? How would you expect the patterns in the other studies to look? How could this information be useful to a scientist?
::除了下文讨论的线性模式外,还有许多其他类型的模式,在许多情况下,根本就没有模式。 如果进行以下四项测试,哪项研究最有可能产生线性模式?你如何期待其他研究的模式?这种信息如何能对科学家有用?-
The temperature in New York City over a 3 year period.
::纽约市3年的温度 -
The length of a person’s hair compared to the number of hours a day he watches television.
::一个人的头发长度与他每天看电视的小时数相比。 -
Pressure as you dive under the sea.
::当你在海底下潜水时 压力很大 -
The altitude of a plane over the course of a flight.
::飞机在飞行过程中的高度
Progress0 / 51.The altitude of a plane from the beginning to the end of the flight is recorded. The data is used to graph a scatterplot. How would you expect the pattern of the graph to look?
::记录从飞行开始到结束的平面高度。 数据用于绘制散射图。 您如何看待图的图案 ?aThe graph will increase, level off, then decrease.
::图表将增加,平整下来,然后降低。bThe data would form a linear pattern.
::数据将形成线性模式。cThe graph will increase, decrease, and repeat.
::该图将增加、减少和重复。dThere is no correlation in this data.
::这一数据没有相关性。
Non-Linear Patterns
::非润滑模式E xamine some graphs that produce patterns that aren’t linear. The first example of this is a scatter plot that displays the height (measured in centimeters) of a sunflower over time (measured in days).
::检查产生非线性图案的一些图案。 第一个例子就是显示向日葵高度(以厘米计)的散射图案(以天数计 ) 。Next, look at a graph that measures energy consumption (measured in kilowatts per hour) in New Hampshire over time (measured in hours).
::接下来,看看一个图表,测量新罕布什尔能源消耗(以每小时千瓦计)随时间(以小时计)而变化(以小时计)。This scatter plot may appear to have no relation but watch what happens when you connect the dots.
::此撒布图似乎没有关联, 但看连接点后会发生什么 。Discussion Questions
::讨论问题 讨论问题The New Hampshire Consumption Over Time graph is an example of a pattern graph. A pattern graph has one general part of the graph which repeats over and over.
::新罕布什尔省在时间上的消费图是图案图的一个例子。图案图有图案的一个一般部分,它反复重复。-
How can you explain the pattern based on the context?
::您如何解释基于上下文的模式 ? -
Who would this graph be helpful to and what could be done with the information?
::这个图对谁有帮助,又能用这个信息做什么?
The scatter plot below has no relation. This means that the and values are completely unrelated and will have no discernible pattern. The points on this graph are completely generated at random . Use the interactive to generate sets of random points.
::下面的散射图没有关系。 这意味着 x 和 y 值完全不相干, 并且没有可辨别的模式。 此图形上的点是随机生成的。 使用交互生成的随机点组 。INTERACTIVERandom Scatter Plot-

Clusters Introduction
::组群介绍A cluster is a group of values that occur around the same location on the graph. A cluster can mean that certain inputs are likely to produce specific results or that the values may affect each other. It is important to be able to recognize and interpret clusters when looking at a scatter plot. The scatter plot below shows a linear pattern and displays a cluster at the bottom left of the graph.
::组群是围绕图形中同一位置发生的一组数值。 组群可能意味着某些输入可能会产生具体结果, 或这些数值可能会相互影响。 重要的是在查看散射图时能够识别和解释组群。 下面的散射图显示一个线性图案, 并在图左下方显示一个组群 。
Cluster Interpretation
::群组口译Below is a graph that compares the year to the eruption size from the Cerro Negro volcano in Nicaragua. Pay close attention to the clusters and try to determine what the cause of these clusters could be.
::下面是尼加拉瓜Cerro Negro火山爆发规模与该年相比的图表。 请密切注意这些群集, 并尝试确定这些群集的原因。Summary
::摘要-
A cluster is a group of values that occur around the same location on the graph.
::组群是指在图中同一位置周围出现的一组数值。 -
If a relationship forms a straight line, the trend is referred to as a linear pattern.
::如果关系构成直线,则趋势称为线性模式。 -
If a relationship does not form a straight line, the trend is referred to as a non-linear pattern.
::如果关系不构成直线,则趋势称为非线性模式。
