Answer: order of test items
Explanation: An independent variable is a variable that is specifically manipulated by a researcher to investigate whether it consequently brings about change in another variable. The other variable, which is measured and predicted to be dependent upon the independent variable, is known as the dependent variable.
In the experiment above, the independent variable is the order or arrangement of the test items. The instructor gave two sets of order to two groups of students to study effect of the order on test scores. The effect on the test scores may be dependent on the order the tests were arranged.
<span>A list of statements is not proved, but Sheila is definitely conducting an experiment. An experiment consists of someone coming up with a hypothesis and then testing to see if the hypothesis is true. Likely, she will take cups of water with varying levels of salt. Then, she will float the same object in the water, and measure its buoyancy to determine the density.</span>
<span>The poison distribution can be used to approximate the binomial distribution when the sample size n is large. This is then calculated using the formula
P(X) = e^-(np) *(np)^x
substituting X= 3
P(3)= e^-(430*1.5/100) * (430*1.5/100)^3
P(3)= 0.00158*268.3
P(3) = 0.42
P(3) = 0.0042%
P= probability of X occurring given n and p
n= sample size
p= true probability
e= exponential constant ~2.718
X=number of sample successes</span>
<span>Choices are
A. permanent migration B. periodic movement C. transhumance D. commuting
And it was B.</span>
Question options
a. a lot of alternative relationships
b. few alternative relationships
c. high satisfaction
d. low satisfaction
Answer:
d. low satisfaction
Explanation:
John here a has a low satisfaction and is therefore considering other options that will satisfy him totally. If John had total satisfaction which would mean that he has zero costs and all benefits he would stick to the relationship so he moves from the relationship if he considers that there are fewer costs in a relationship with another person and can only stay in that relationship if it has the lowest costs and highest benefits compared to other relationships.
