15.6.2.2. Interpolation methods for missing data

Try these first

1. 1.

   What is interpolation?

   Hint

   Think about how you fill in gaps between two known numbers.

2. 2.

   What is linear interpolation?

   Hint

   Remember 'linear' relates to 'line.'

3. 3.

   What is the main purpose of using interpolation methods?

   • To visualize data
   • To estimate missing values
   • To analyze trends

   Hint

   Consider why complete data is important.

4. 4.

   True or False: Linear interpolation can only be used with evenly spaced data.

   • True
   • False

   Hint

   Consider the straight path of a line.

5. 5.

   Given the rainfall data for the hours: 8 AM - 10 mm, 9 AM - 15 mm, and unknown for 10 AM, employ linear interpolation to estimate the missing value.

   Hint

   Calculate the average value based on adjacent known values.

6. 6.

   You have three rainfall points: 2 PM (20 mm), 3 PM (25 mm), and 4 PM (unknown). Describe how you would use spline interpolation to estimate the value at 4 PM.

   Hint

   Focus on fitting a curve rather than connecting with a straight line.
