Answer:
c). only one design involves observing the same participants in each group
Explanation:
A repeated-measures design differs with a matched-samples design in away that only on design involves observing the same participants in each group.
Option a). is wrong because both the matched-samples design as well as a repeated-measures design are grouped together under related-sample design.
Option b). is wrong because both the repeated-measures design and the matched-samples design eliminates between-persons variability. However one does better than the other.
Option d). is wrong because both the designs increases the power to observe an effect.
Hence the correct option is ---
c). only one design involves observing the same participants in each group
Since Walt is transitioning from being a shy person to volunteering in a local animal shelter, we can conclude that Walter is experiencing balance in the social dimension of his life.
The social dimension of life as it is being used here tells us that Walt is now better suited to relating with the society.
In the beginning of the question we read about his shyness. But by trying to volunteer, it is obvious that he is in need of companionship given that he is lonely.
He is therefore trying to balance his lonely weekend by volunteering.

Answer: hypothesizing scores will be equivalent if they play the same amount of time.
In order for Kayla to be sure why her male and female friends scores vary, she should hypothesize their scores for playing the same amount of time because that's the only differing factor that she has observed.
We know that <span>L=Iω</span>
That is Angular momentum is equal to product of moment of inertia and angular velocity.
Now differentiating with respect to time,
<span>dL/dt=d(Iω)/dt</span>
But we know that the rate of change of angular momentum is equal to net external
torque i.e.
<span>
dL/dt=τ</span>
therefore
if no exterannal torque is acting on the body i.e. <span>
τ=0</span>then <span>d</span><span>L</span><span>/</span><span>d</span><span>t</span><span>=</span><span>0</span>
in other words
<span>d(Iω)/dt=0</span>
because <span>
dL/dt=d(Iω)/dt</span><span>
Hence angular momentum is conserved or angular momentun does not change with time if the net external force acting on the body is zero.
hope this helps</span>
