Explanation: Alexandra is investigating exercising habits using the ratio scale. The ratio scale is a type of scale used in variable measurement allows researchers to compare the intervals or differences. It is quantitative in nature and possesses a zero point or character of origin representing the total absence of the variable being measured. This means that there can be students who do not exercise at all. In simpler terms, ratio variables have all the properties of interval variables including a real absolute zero.
To investigate exercise, Alexandra is using a ratio scale.
Explanation:
The ratio scale permits the comparison of differences in value when it comes to measuring data. In ratio scale, there is the option of true zero. There is also a specific order between the options. An example using ratio scale concerning the topic Alexandra is studying is:
Xavier studies a unit of world history until he believes he knows it well. He then goes over it several more times. He is using the study skill called <u>overlearning.</u>
Explanation:
Overlearning means to practice newly acquired skills beyond the point of initial mastery. The term is also often used to refer to the pedagogical theory that this form of practice leads to automaticity or other beneficial consequences.
