Important Formulas to Remember
Burn these into your brain (or just highlight them in the notes):
- Mean (Grouped Data): xˉ=∑fixi∑fi\bar{x} = \frac{\sum{f_ix_i}}{\sum{f_i}}
- Mean (Step Deviation Method): xˉ=a+h⋅∑fiui∑fi\bar{x} = a + h \cdot \frac{\sum{f_iu_i}}{\sum{f_i}}
- Variance: σ2=∑fi(xi−xˉ)2∑fi\sigma^2 = \frac{\sum{f_i(x_i – \bar{x})^2}}{\sum{f_i}}
- Standard Deviation: σ=σ2\sigma = \sqrt{\sigma^2}
- Coefficient of Variation: C.V.=σxˉ×100\text{C.V.} = \frac{\sigma}{\bar{x}} \times 100
These formulas aren’t scary once you understand what they actually represent.

🧾 Summary of the Chapter
- Statistics is the science of collecting, organizing, analyzing, and interpreting data.
- Central tendency (mean, median, mode) helps in understanding data centers.
- Standard deviation and variance show the spread or dispersion.
- Step-deviation and assumed mean methods save time in exams.
- Coefficient of variation is used to compare consistency across datasets.
Understanding these can not only help you in exams but also in subjects like economics, geography, and even psychology!
