Random samples of? 5-year-old, 6-year-old, and? 7-year-old children are obtained. Each child is given a standardized? problem-solving task, and the psychologist records the number of errors. Test whether there are any significant differences among the three age? groups; use the .05 level of significance.The data are as? follows:?5-year-olds: 5,? 4, 6?6-year-olds: 6,? 4, 2?7-year-olds: 0,? 1, 2?a) create a JASP data file?b) Use JASP to do a? one-way ANOVA?c) if? F-value is? significant, add the protected? t-tests to the JASP analysis?d) Answer the? following:Null? hypothesis:A.There are differences in? problem-solving betweeen? 5, 6, and? 7-year old kids.B.There are no differences in? problem-solving between? 5, 6, and? 7-year old kids.The? F-value is?F(____, _______?)= _____, p? = .031True or? false: There are significant differences between the age groups of children.TrueFalseThe protected? t-tests showed one signifcant difference. Which? one?A.5 year olds differed from 7 year oldsB.6 year olds differed from 7 year oldsC.5 year olds differed from 6 year oldsWhat is the interpretation of the significant? finding:A.5 year olds made more errors than 7 year oldsB.5 year olds made fewer errors than 7 year oldsC.5 year olds made more errors than 6 year oldsD.6 year old made more errors than 7 year oldsMathStatistics and Probability PSYC 3301
