Use the dаtа set here fоr this questiоn. Yоu will аlso use the same data set for the next question. The file contains information from students in a college class. It contains their class standing, Year. It contains their scores on their homework assignments; these are H1-H14. It contains the number of homework assignments effectively missed, HM; if the student scored less than 50% then it is counted as "effectively missed." The students' number of absences is Absences. Their scores on the mandatory practices exams are PE1, PE2 and PE3. Their initial scores on three midterms are E1RAW, E2RAW and E3RAW; the actual exam scores included a curve and their was a final exam score that is not included in the data set. Their end of semester overall course percentage is the variable FinalScore. a) What is the median FinalScore? [a_73pt19]. b) Construct a histogram of the FinalScore. Choose the best answer, (i) its distribution appears roughly normal, (ii) its distribution is roughly uniform, (iii) its distribution appears more like an F distribution than either the normal or uniform distribution. [b_i]. c) Construct a boxplot of Absences. T/F: there is at least one outlier for Absences. [c_F]. d) Construct a scatterplot with Absences on the horizontal axis and FinalScore on the vertical axis. T/F: the scatterplot shows a negative relationship between the two variables, i.e., as Absences increases FinalScore decreases. [d_T]. e) Regress FinalScore on all of the explanatory variables. The summary results should show that there are 25 and 61 df for your F statistic. That is, there should be 25 explanatory variables; Year has multiple categories which you can create yourself or allow R to create by simply including Year in the model. What is the R^2 for this regression? [e_pt9688]. f) Which class of students has the highest expected score based on the regression alone? [f_Junior]. g) Run another regression with FinalScore as the dependent variable and all of the other variables as explanatory variables except the class variables (i.e., no Year and no dummy variables for Sophomore etc). You should have 22 explanatory variables in this model. In this model, which variable has the highest level of statistical significance? That is, which variable is "most" statistically significant. [g_E1RAW]. h) What is the largest vif for this model? Find the variable with largest vif for the set of 22 explanatory variables in the model. [h_19pt3]. i) T/F: the vif in part (h) indicates that multicollinearity is a concern in this model. [i_T]. j) Conduct the forward selection procedure with FinalScore as the dependent variable and the 22 explanatory variables from part (g). Use a 0.2 cutoff for your p-value or significance level. What is the first variable chosen? [j_HM]. k) Once the procedure is complete you have a model with p explanatory variables. With the p variable model, is the first variable chosen (see part j) statistically significant at the 0.2 level? [k_no]. l) Use the model chosen by the forward selection procedure. That is, construct a model with the variables selected in the forward selection procedure from part (j). What is the R^2 for this regression? [l_pt9649]. m) Using this most recent model from part (l) which has the variables selected from part (j), conduct a test for heteroskedasticity (use the test we covered in the course). Use an alpha value of 0.1 for your test. T/F: the errors appear to be heteroskedastic. [m_F]. n) This model contains E1RAW, E2RAW and E3RAW; if your forward selection procedure did not have those three variables then something is wrong and you might go back and check your code. In the course each of those exams was worth 20% of the final grade. For various reasons though, the actual coefficient on any of those variables might not be 0.2; students could replace one of those scores with the final exam score, the exams were curved, and doing "well" or "poorly" on an exam might be correlated with doing "well" or "poorly" on other assignments. Test the hypothesis that the coefficient on each of the raw test scores are jointly 0.2, i.e.,
Thus fаr in this cоurse we hаve discussed the develоpment оf children in the Sensorimotor аnd Pre-Operational stages of development. List the major GOAL which must be learned (cognitive development) in each of these stages before a child can successfully move on to the next stage of Concrete Operations. Give a brief definition of both goals.
