TL;DR; 
Quantum measurement for full and partial qubits, with examples. Quantum state. Pure state.
Please refer to the previous articles:
Qubit, An Intuition #1 — First Baby Steps in Exploring the Quantum World” for a discussion on a single qubit as a computing unit for quantum computation.
- "Qubit, An Intuition #2 - Inner Product, Outer Product, and Tensor Product" for a discussion on two-qubits operations.

For an introductory helicopter view of the overall six articles in the series, please visit this link “Embarking on a Journey to Quantum Computing — Without Physics Degree.”

In the last two articles on the “Qubit, An Intuition” series, we have discussed the basics of a quantum bit (qubit) and two-qubits operations: inner product, outer product, as well as the tensor product. In this article, we discuss quantum measurement, the observation of quantum states that change the wave function Psi |Ψ> from a superposition state to a pure quantum state.
