[quote="goodyear2013"]In an experiment, one thousand nine-year-old children were allowed to choose whether to participate in a program in which the researchers taught
them dance during the daily break from their lessons. Four hundred of the children chose to participate for at least one year. At the end of the year,
researchers found that the children who had participated had significantly better balance, on average, than those who had not.
The researchers hypothesized that dancing resulted in a sustained improvement in the children's sense of balance.
It would be most helpful in evaluating the researcher's hypothesis to know whether the researchers ___1___ prior to having __2__.
Select
Researchers for the phrase that fills the blank labeled 1 in the given statement, and select
Prior to for the phrase that fills the blank labeled 2 in the given statement to create the most accurate statement on the basis of the information provided. Make only two selections, one in each column.
1:Researchers | 2: Prior to
0 0 tested the children's ability to dance
0 0 designed a second experiment
0 0 divided the children into the two experimental groups
0 0 tested the children's sense of balance
0 0 taught dance to the children through the dance program
Hi, I found this question hard. In fact, not sure where to start with.
Can anyone explain this for me, please.
Hi
goodyear2013The passage says that, researchers "taught dance to childerne" and after one year they concluded that the children who had participated had significantly better balance, on average, than those who had not. And thus Dancing helped
Now as the result is based on the "average", if some of the children who took the program already knew dancing then the resulted average would stand incorrect.
Therefore Ans :
the researchers ___1.tested the children's ability to dance___ prior to having __2.taught dance to the children through the dance program__.
Hope it helps.
