Statistical Measures
1. This question has 3 part(s).
1.1. A veterinary nurse records the weight of puppies (in kg) at birth and again at their eight week check-up. The table below summarises the weight gain of 50 small breed puppies over their first eight weeks.
Weight gain w (kg) | Number of puppies f |
|---|---|
0.0 ≤ w < 0.5 | 1 |
0.5 ≤ w < 1.0 | 8 |
1.0 ≤ w < 1.5 | 19 |
1.5 ≤ w < 2.0 | 18 |
2.0 ≤ w < 2.5 | 4 |
Use linear interpolation to estimate the median of the weight gain of the 50 puppies.
1.2. Give a reason why it is not possible to determine the exact median for this data.
1.3. The head veterinarian directs the nurse to monitor all puppies whose weight gain lies within the bottom 20% of the data set.
Explain why, without further information, the veterinary nurse would have to monitor over 50% of the puppies to be sure of satisfying this instruction.
