Answer:
example of construct validity
Explanation:
Construct validity refers to how accurate a study can measure / provide data about the things it claim in the initial description. From the case above, Tara's study claim that it measure<em> 'how social college students are with friends at lunch compared to at dinner' . </em>
In order to measure this, Tara only use 'duration of eye contact' as an indicator of measure it.
The thing is, Social interaction is done with many type of actions, including spoken communication, skin contact, laughter, opened body language ,etc. Only using eye contact will cut off the people who rely their socialization process on these other actions. Because of this, we can say that this study is lacking in validity.
Answer:
Total 6 sample will required.
Explanation:
We know that variable are of two types
1. Independent variable:
Those variable does not depends on the other variables.
1. Dependent variable:
Those variable depends on the other variables.
Ex: f(y)= 23 x + 2
Here x is independent variables and y is dependent variables.
In the given question
One dependent variables have two independent variables.
First IV have two levels and second IV have 3 levels
So the total sample required = 2 x 3 =6
Total 6 sample will required.
The correct answer would be option B, Can broad jump slightly farther.
By age 5, boys can broad jump slightly farther than girls.

So when comparing boys and girls on the basis of broad jump, then it is seen that boy's motor skills(muscle movement) is slightly better than the muscle movement of the young girls.
This is the reason that boys can jump lightly farther than girls.
It is believed that the reason why boys have slightly better muscle movement in many fields like batting, skipping, running, etc, is that they have a social pressure on them. Being boys, they are expected to be more powerful since early childhood. That is why they have better motor skills.
