Liam, a psychology teacher, designs a questionnaire to determine the most preferred social media among students in his classroom. which measure of central tendency should he use to get an accurate idea?

Mode

Step-by-step explanation:

A central tendency measure (also referred to as center or central place measure) is a descriptive measure that tries to define a whole collection of information with a  single variable representing its distribution center or middle.

There are three primary key trend measurements: mode, median and the mean.

The mode is a distribution's most common value.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

no this is a nonlinear negative
