Data Handling Solver

About Data Handling

Data handling is the first taste of statistics. The 9 solved problems cover the three measures of central tendency — mean (the arithmetic average), median (the middle value of the sorted data), and mode (the most frequent value) — along with reading and drawing bar graphs and pie charts. The questions follow the CBSE Class 7–8 pattern: you are given a short table or graph and asked to compute one or two measures, or to identify which measure is most appropriate for the kind of data shown.

What this calculator does

• Step-by-step working. Every intermediate line is shown, in the layout examiners reward in CBSE / ICSE and university scripts.
• Graphs where they help. Functions and equations are plotted so you can see the result rather than just read it.
• Verification. The answer is substituted back into the original problem so you know the working is consistent.
