Statistics — formula, example and practice

Mean, median, mode and graphs. Board papers ask interpretation, not only formulas.

Content type: original worked example. Not labelled as a previous-year question.

Formula

Mean = Σx / n · Median = middle value of an ordered list

Describe a data set. Mode is the most frequent value.

What you should learn here

Grouped data uses class marks. CBSE asks ogive / cumulative frequency more than SSC does.

Worked example

Question. Mean of 4, 8, 10, 6?

Solution. 28/4 = 7.

Common mistake. Finding the median without sorting.

When to use the shortcut. For even n, median is the mean of the two central values.

FAQs

Are these previous-year SSC questions?

No year or shift is claimed on these pages. Each maths section has 150 original practice MCQs. When a verified source database exists, a question will show exam + year; until then it is practice.

Where are Class 10 board formulas?

The CBSE formula sheet at /cbse/class-10/mathematics/formulas/ stays the canonical board list. This maths hub links to it instead of copying every line.

Do you publish tricks that are only sometimes true?

Every shortcut page states when the trick must not be used. A speed trick that fails on close options is not published as if it were a theorem.
