WebIn National 4 Lifeskills Maths use statistics to analyse and compare data sets using mean, median, range, inter-quartile range, and standard deviation. ... Finding the median from a frequency table. WebThe usual thing to do when finding the median of a frequency distribution is to figure out which group contains the median, and then interpolate within that group. The calculation works like this: With 22 values, the median would normally be the average of the 11th and 12 values. The first two groups contain only up to 9 data values, and adding ...

Step 4: Identify the class in which the median falls. (Median Class is the class where n/2 lies.) Step 5: Find the lower limit of the median class(l), and the cumulative frequency of the class preceding the median class (c). Now, use the following formula to find the median value. ceramic copper pots induction cooktop
