A box plot (sometimes also called a âbox and whisker plotâ) is one of the many ways we can display a set of data that has been collected. 2. On the cumulative frequency graph, we need to locate 50 on the cumulative frequency axis and find the corresponding weight in kilograms. From the graph, we can see that the lower quartile is 10.5 and the upper quartile is 12.4, so: \text{Interquartile range } = 12.4 - 10.5 = 1.9\text{ seconds}. Box Plots. Plot Y range is 42 − 6 = 36 5. The median is the \dfrac{7+1}{2} = 4th term, which is 312. Box plots (also known as box and whisker plots) are used in statistics and data analysis. Some of the worksheets for this concept are Box whisker work, Making and understanding box and whisker plots five, Interpreting box and whisker plots practice, Box and whisker plot work with answers, Box and whisker plot work with answers, Box and whisker plot work with answers, Box and whisker plot level 1 s1, Five … Store A’s median is about 43, and Store B’s is about 51. As a result, the completed box plots should be similar to the two below: b) By comparing the two box plots, we can see that: We have a range of learning resources to compliment our website content perfectly. Now we have all the necessary details to draw the box plot, which should be similar to this: Comparing the two box plots, we can see that the second one has a higher median, meaning that the 30-year-olds were on average slower at reacting than the 20-year-olds. Its range and inter quartile range are, Four of Store B’s key values are greater than Store A’s. From the graph, we can see that the smallest value is 10 and the largest is 15.8, so: \text{Range } = 15.8 - 10 = 5.8\text{ seconds}. Compare the distribution of amount spent in 2014 and 2015. The median time is greater for the year 9 class. compare to the 50-animal sample. Group A; Group B; look at which box plot has a greater distance from the median to the minimum or maximum value, respectively. Their total marks, out of a possible 100, were recorded. Box-and-Whisker Plots About this Lesson This is a foundational lesson for box-and-whisker plots ... and compare dotplots (line plots., stemplots, and bar graphs. The top 50% of shopping times ? For questions 1 ... For questions 12 – 23, refer to the box & whisker graphs below that compare homework time per night with TV time per night for the same group of sophomores. Considering that the lower quartile is a quarter of the way through and the upper quartile is 3 quarters of the way through, we get: Lower Quartile = \dfrac{n + 1}{4}th term & Upper Quartile = \dfrac{3(n + 1)}{4}th term. The top 50% of shopping times ? Using the box plot, determine the range and interquartile range. Draw a box plot to show the distribution of the Weight Watchers members.
