Lab Assignment 1
1PSYC 2260 Assignment 1
Due Date: January 29, 2024 at 11:59 PM on UM Learn (Assessments > Assignments Folder)
Total Marks: 48
Purpose: In this assignment, you will perform hand calculations, interpret a frequency distribution, and
identify the appropriate measures of central tendency. You will practice data entry, creating a histogram,
generating a frequency table, and obtaining measures of central tendency. There are 3 big questions and
multiple sub-questions under each. By the assignment release date, you already have knowledge for Q1. As
lectures and lab proceed, you will gradually gain knowledge about Q2 and Q3.
*********************INSTRUCTIONS (Read Carefully)*************************************
1. SAVE your assignment as a PDF file before submission. To do so, Click File, Save As, and choose the
location, then click the drop down menu beside “Save as type” and select PDF.
2. Submit your PDF format assignment via UM Learn assignment submission folder. Make sure to save
the submission email sent to you as a proof. Note that only the most recent submitted copy will be saved
and graded.
3. You can keep the question wordings in this document and type your response in blue color
underneath each question or into the table for filling out the cells.
4. For questions that specify to “show calculation”, show one step of calculation by plugging in or
writing out the scores according to the appropriate formula, in addition to providing the result (round
to three decimal places unless the result is an integer).
*********************INSTRUCTIONS (Read Carefully)*************************************
Q1. Summation Notation and Basic Computation
A. Complete the following table for each of the four X values: [4 marks]
X (X + 5) (X + 5)²
1 6 36
3 8 64
2 7 49
5 10 100
B. Using the 4 values of X from Q1.A, calculate the following (show calculation): [8 marks]
a. ∑X = 1+3+2+5 = 11
b. (∑X)/N = 4/11 = 2.75
c. ∑(X + 8) = 9+11+10+13 = 43
d. ∑(X + 8)2 = 81+121+100+169 = 471
