This week you have been introduced to descriptive and inferential statistics. In the article "Household Chaos - Links With Parenting and Child Behaviors" you read the following in the results section: "Table 1 contains means and standard deviations for all the measures used in the study. In addition, correlations between parental and child reports of parenting were analyzed and ranged from negligible and insignificant to moderate in magnitude (Range r=.01 to r=.27)." Explain the following: 1) What is a mean and a standard deviation? What do they tell us? 2) Why do the researchers say there is a range from a negligible to moderate correlation (Talk about what the r scores mean)?
