Solution

Solution Steps

The sample described is a self-selected sample because it relies on individuals to take the initiative to participate, which can lead to bias as it may not represent the entire population.

Step 1: Identify the Sample Type

The scenario describes a situation where the student government association invites students to call in and express their opinions about a new grading policy. This method of sampling allows individuals to choose whether or not to participate, leading to a specific type of sample.

Step 2: Classify the Sample

Since participation is voluntary and relies on students to self-select into the sample, it is classified as a self-selected sample. This type of sampling can introduce bias, as those who choose to respond may have stronger opinions than the general student population.
