VARIABLES, MEASURES, AND SPSS ASSIGNMENT INSTRUCTIONS
OVERVIEW
This Homework: Variables, Measures & SPSS Task is designed to evaluate your understanding of the ideas and purposes coated up to now in PSYC 510: Analysis Strategies and Statistics in Psychology I. This explicit module introduces extra introductory ideas of analysis design together with sorts of measures generally used within the subject, variables, scale of measurement, and whether or not variables are discrete or steady. Definitions, purposes, and significance of reliability and validity are coated, and we’re launched to essentially the most generally used statistical software program in our subject – SPSS.
INSTRUCTIONS
Make certain you will have reviewed this module’s Be taught part earlier than finishing this Homework: Variables, Measures & SPSS Task. This Homework: Variables, Measures & SPSS Task is value 60 factors. Every Question Assignment is value three factors besides questions #1 – three, that are value four pts. Six factors are awarded for general mechanics/construction.
• Half I incorporates basic ideas from this module’s Be taught part.
• Half II requires use of SPSS. You’ll have to take “snips”, display pictures and/or copy and paste out of your SPSS to put solutions inside this file. Be sure to solely insert related and legible photographs. Failure to take action could have an effect on the mechanics / construction factors for this project.
• Half III is the cumulative part. These could embody brief reply and/or use of SPSS however will overview materials from earlier module(s).
• Instructions for every subsection are supplied within the prime of every desk (within the grey shaded areas). Solutions ought to be positioned the place indicated (wherever there may be “ANSWER”).
