A researcher was interested in comparing the academic motivation of identified gifted 4th grade students and 4th grade students who were not identified as gifted.   100 gifted 4th grade students and 100, 4th grade students who were not identified as gifted were randomly selected and were administered a 10 item academic motivation questionnaire (Cronbach alpha = .96).  The responses to the questionnaire were combined to form an overall academic motivation score. What does Cronbach’s alpha evaluate?  

King presents in Table 1 an effect size of 1.33 for the summarizing group’s posttest scores compared to the notetaking group’s posttest score..  Interpret this value

Calculate  the “effect size” for the following study:  EXPERIMENTAL GROUP                             CONTROL GROUP    Mean=100                                                          Mean=90     SD=50                                                                 SD=50  

For  the following statement that might be found in a test manual, indicate what type of evidence of MEASUREMENT VALIDITY is indicated by the statement. A panel of experts reviewed the 50 items on the math test and judged the items to be clearly written and covered the instructional objectives.

Which of the following was NOT a type of manufacturing that existed BEFORE the Industrial Revolution?

READ THE FOLLOWING CAREFULLY You can alert the proctor that you are DONE and ready to SCAN YOUR WORK and SUBMIT.  Wait for the proctor to join you before getting your phone to scan, email, and upload your work. NOTE:  If the proctor does not join you within a reasonable amount of time (5 minutes), it is okay to begin. STAY ON CAMERA while completing your scanning and uploading. Scan your work into a SINGLE pdf document.  Be sure to “keep scanning” so you create a SINGLE pdf. Email this scan/pdf to yourself.  Save the scan/pdf.  MAKE SURE you know where you saved it – and rename it.  Ex:  Exam 1  Your Name Upload this Scan into this question. Submit the Exam DO NOT try to upload pictures, jpegs or multiple files.  It must be ONE SINGLE PDF file.

Solve.  Show all steps and use a horizontal format for add and subtract as shown in the class video lesson.  Use the    button as needed to insert/type math equations, symbols, etc. You will need this to show any divisions (fractions) when solving equations. TYPE YOUR WORK IN THE BOX BELOW.     NO WORK = NO POINTS                   In order to show work, use the Math Editor in Canvas ( Insert, then the   button) to insert/type math equations, symbols, etc. Hit enter between each step of the solving process so that your work is “vertically stacked” Use the fraction template   in the Math Editor to show division (as needed).  Don’t use the
