Would this below be an example of convenience sample and why:
Zooms produces computer games. The quality control department of Zooms has a procedure to inspect its games. During the first hour of production the manager picks a random value between 1 and 60. If the number is 35 then at exactly thirty five minutes past the hour, for that hour and for every other hour after that during that day, she sends her assistant to pull a copy of the software game program from the assembly line. The programs pulled will get put through a complete testing process.
