Hello all, I've got some homework on grouped frequency tables. I can work out the mean no problem but I'm totally stuck on finding the median. I know you how to tell if you fancy someone The following code doesn't use replication, and it uses R builtins (for the dot product especially) as much as possible so it is probably more efficient that solutions that use sum(V1 * V2).

- 2007-01-23 · The midpoints are used as class marks for making the frequency polygon.
- First add columns with class width and frequency density to the table. Now you can draw your histogram. Note: In an exam you might just be given a histogram like this and asked, for example, how many children are between 80cm and 90cm.
- Cumulative frequencies are easy to calculate from a frequency table. Cumulative frequency graphs can then be used to estimate the median of a set of data. In this section we also look at the idea of Cumulative frequency graphs can then be used to estimate the median of a set of data.
- Often data is presented in the form of a frequency table. For example, the data in range A4:A11 of Figure 1 can be expressed by the frequency table in range C4:D7. Figure 1 – Frequency Table. The table in Figure 1 shows that the data element 2 occurs 4 times, the element 4 occurs 2 …
