If the range is large, then the mean median or mode might not represent the data very well. Whereas if the range is small, then they will represent the data well. In this video, we learn all about The Range in more detail. 极差为均值, 中值和众数提供了一个情景. 如果极差偏大, 得出的均值, 中值和众数可能无法很好的代表数据. 如果极差偏小, 它们的代表性就好. 通过本视频，我们将更加细致的了解极差. 访问我们的网站 www.fuseschool.org，在那里我们所有的视频都被精心按主题和订单分类，查看下我们还准备了什么。留言、点赞并与其他同学分享吧。你可以提问, 也可以回答问题，我们的老师也会为大家解惑。 这些视频可用于翻转课堂或用作复习辅助。 使用 fusesschool 平台和其app可获得更深入的学习体验: www.fuseschool.org 本教育视频资源是开放且免费的，在知识共享协议下: 署名-非商业性CC by nc(查看许可契约): http://creativecommons.org/licenses/by-nc/4.0/ ). 你可以下载这段视频或在非盈利组织和教育机构使用。如果想修改视频，请联系我们: info@fuseschool.org

In this video, we are going to look at parallel lines. To find the equation of parallel lines, we still use the y=mx + c equation, and because they have the same gradient, we know straight away that the gradient ‘m’ will be the same. We then just need to find the missing y-intercept ‘c’ value. VISI
Plants have developed responses called tropisms. A tropism is a growth in response to a stimulus; so light and water in the plant’s case. There are different types of tropisms: Positive tropisms are when growth is towards the stimulus - so the plant growing towards the light to maximise the stimul
