Worked Solution & Example Answer:The graph shows the body temperature of 60 people - Edexcel - GCSE Biology - Question 3 - 2012 - Paper 1
Step 1
Complete the sentence by putting a cross (X) in the box next to your answer. The range in body temperature is
Answer
To determine the range in body temperature, we need to find the difference between the maximum and minimum temperatures from the graph.
The minimum temperature is approximately 36.8 °C and the maximum temperature is approximately 37.9 °C.
Calculating the range:
Therefore, the correct answer is B. 1.1.
Step 2
State the type of variation, shown in the graph, that results in a normal distribution curve.
Answer
The type of variation shown in the graph is continuous variation. This is characterized by data that can take any value within a range and often results in a normal distribution curve, where most values cluster around a central peak and the probabilities for values further away from the mean taper off symmetrically.
