I’m think the answer might be false
Answer:
candy and no-candy condition
Marnie's strategy used researchers to find out the number of misbehaviors among the children( little enough to fit in shopping cart). She tries to pick chilren randomly by picking out every fifth child who is little enough to fit in cart for her research. She limits her research to certain age group.
Age group is the extraneous variable in the experiment
Ethical challenge: The researchers followed the child. So they had to be careful
mode in candy condition: 3
range in no candy condtion is 3
They can reduce number of mis-behaviors by disciplining them.
Explanation:
Independent variable: Candy and no-candy condition.
Her strategy is to pick chilren randomly so she directs researchers to pick every fifth child. She also restricts her research to a certain age group. The age group is restricted by making sure that child is small enough to fit in shopping cart.
age group. She controlled this by making sure children were small enough to fit in shopping cart.
The researchers followed the child around the store which is unethical. They must have been careful not to get noticed.
range in no-candy condition: 4-1=3
authoritative parenting help to discipline the children
Answer: No. The student is not right.
Explanation: The central limit theory states that if the sum of independent identically distributed random variables has a finite variance, then it will be approximately normally distributed.
Increasing the size of samples taken from a population, will make the sampling distribution of X look more and more Normal.
