**Cumulative Frequency Free Maths Worksheets**

We can find the interquartile range or IQR in four simple steps: Order the data from least to greatest Find the median Calculate the median of both the lower and upper half of the data The IQR is the difference between the upper and lower medians; Step 1: Order the data . In order to calculate the IQR, we need to begin by ordering the values of the data set from the least to the greatest...

**Median and Interquartile Range of a frequency table**

the median and interquartile range Cumulative Frequency A cumulative frequency diagram is a graph that can be used to find estimates of the median and upper and lower quartiles of grouped data. The median is the middle value when the data has been placed in order of size The lower quartile is the â€˜medianâ€™ of the bottom half of the data set and represents the value Â¼ of the way through the...The graph below shows how the interquartile range is found and how quartiles are related to a Box Plot. Use the graph to calculate an approximation for the interquartile range for your data. Textbook help MYP 5 PLUS page 196 Section H, example 10 as needed.

11/11/2007Â Â· Cumulative Frequency- Median & Quartiles. HELP.? Find the nth result in the numerically ordered list or frequency table. You will then be able to find the median in the set of results. We know that the median divides the data into two halves. We also know that for a set of n ordered numbers the median is the (n + 1) Ã· 2 th value. Similarly, the lower quartile divides the bottom half of how to find the midsegment of a trapezoid with variables 27/04/2009Â Â· 1)Find the value which is 75% of your total number of values, for example, if you had 40 car prices, draw a line across from '30' on your cumulative frequency axis, and â€¦.
