Some fundamentals from a simple tape measure


Learning goals

As we embark on this topic, ask yourself: Can I define and distinguish between the following terms?

  • Parameter
  • Observable
  • Measurement
  • Observation
  • Data
  • Statistic
  • Estimate
  • Error
  • Residual

The main learning goal of this topic is to help you do this.

Really mastering this will provide you with the foundation we need to go on and learn about the three key mathematical models used in geomatics and geospatial applications, to follow in our next topic.

My notes

Here are my lectures notes – the ones I wrote up when I lectured on this topic. They’re not perfect, but if you’re in my class then they should be helpful when you go to create your own “perfect” set of lecture notes.

When you’re ready, proceed by working your way through the self-assessments (under “Lesson Content”) below.

Once you’ve clicked through those, you can use the button at the bottom of the screen to move on to the next lesson (or to finish up once you get to the last one).

The following schedules are for Alex’s in-class students:
