Answer:
4. . Selecting a biased sample
Explanation:
A bias sample is a type of sample that has characteristics noticeably different from those of the population.
The bias sample selection procedure always favors the selection of some individuals over others. What this results to is that at the end of the day, the best sample from the population wont be selected.
The findings gotten from a bias sample are mostly confounded, untrue, can not be relied on in most cases, etc.

Workers can protect themselves from accidents or being harmed when they are working on or near any construction zone by wearing high visibility reflective clothing in order to be easily seen by any moving machine operator. Directing traffic in construction zone, and walking quickly does not guarantee a safe working environment.
Students can learn to mentally give themselves a pat on the back when they finish a task or stop at regular intervals to assess what they have done. This is called Self-regulated learning.
Self-study refers to the ability to understand and control one's learning environment. Self-adjusting skills include goal-setting, self-monitoring, self-teaching, and self-reinforcing (Harris & Graham, 1999; Schraw, Crippen, and Hartley, 2006; Shunk, 1996).
In addition to fostering personal responsibility for learning, self-teaching also enhances learning content. Self-regulatory practices improve the coding of knowledge and skills in memory, especially reading and writing.
According to Pintrich's (2000) model, the SRL consists of four phases: (2) Monitoring; (3) Control; (4) Reactions and reflexes. Each of them has four different regulatory areas: cognition, motivation/emotion, behavior, and context.
