Sun Mi is designing a questionnaire on loneliness. She is concerned that some features of loneliness are similar to depression and to low self-esteem. Which type of validity does she need to show to demonstrate that her questionnaire assesses loneliness and not depression or low self-esteem?

Discriminant validity

Explanation:

Discriminant validity could be explained as proving to show that contents that are not meant to be related are actually unrelated. This helps the audience addressed to know the difference in the information so they don't mix things up and are misinformed. In other for Sun Mi to validate his question considering people may misunderstand it for depression and low self-esteem instead of loneliness, he has to implemet a Discriminant validity in the questionnaire so the audience understand it in the perspective he is looking at.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)

chavez's example shows that nonviolent protest can work well. it shows that one nonviolent man can stop a mob, which proves chavez's point and persuades people to protest nonviolently.
