Biology

While the IB Biology syllabus doesn’t provide a formula booklet, there are several key formulae that are essential to know for your exams. In this post, we’ll highlight the formulae you should be familiar with.&nbsp;&nbsp;&nbsp;<h2 style="text-align:center;">IB Biology Formula Booklet</h2>&nbsp;&nbsp;<figure class="table"><table><thead><tr><th>Name&nbsp;</th><th>Formula</th><th>Notes/Annotations</th></tr></thead><tbody><tr><td>Mean</td><td>Mean = Σx/nwhere Σx is the sum of all data values and n is the number of data values</td><td>Remember: Sensitive to extreme values (outliers), which can skew the mean.</td></tr><tr><td>Percentage change</td><td>% change = [(Final value − Initial value) ÷ Initial] × 100</td><td>Common mistake: Dividing by the final value instead of the initial value; always use the initial value in the denominator.</td></tr><tr><td>Magnification</td><td>M = I ÷ Awhere I is the Image size (measured with a ruler) and A is the Actual size (according to scale bar)</td><td>Remember: You can rearrange the formula to find the image size or the actual size.</td></tr><tr><td>BMI</td><td>BMI = mass (kg) ÷ [height (m)]2</td><td>Remember: BMI is a general guideline and may not account for muscle mass or body composition.</td></tr><tr><td>Energy in food</td><td>Energy (kJ/g) = (Water mass × ΔT × 4.2) ÷ Mass of foodwhere ΔT is the temperature change of the water (in °C)</td><td>Remember: 4.2 represents the specific heat capacity of water in J/g°C; convert to kJ by dividing by 1000 if needed.&nbsp;</td></tr></tbody></table></figure>&nbsp;&nbsp;&nbsp;We hope you found this post helpful.
