Lab 1 Report Tutorial: 1.0 Introduction
• Think of the INTRODUCTION as the “who cares” or “so what” section –this is a brief space to convince the reader that this report is important, relevant, interesting, and that they should take the time to read it.
• Include the purpose or objectives of the laboratory;
“ This report discusses an experiment to study the relationship of temperature and pressure of an ideal gas (air) that was heated in a closed container. Because the ideal gas was in a closed container, its volume remained constant. The objective of the experiment is to test whether the ideal equation of state holds. In the equation,
pV = mRT,
where p is the pressure the gas, V is the volume, m is the mass, R is a constant, and T is temperature. This report presents the procedures for the experiment, the experiment’s results, and an analysis of those results.”

5
Lab 1 Report Tutorial: 2.0 Methodology
2.2 Equipment
• What is the hardware and software employed to run the experiment? • What tools are used for presenting the experimental task?

6
Lab 1 Report Tutorial: 2.0 Methodology
2.3 Procedure
• Step-by-step explanation of what was done in the exploration.
• Everything should be described in the order in which it occurred.
7
Lab 1 Report Tutorial: 2.0 Methodology 2.4 Description of Variables
• Describe independent and dependent variables ;
• An independent variable is the variable that is
changed or controlled in the experiment;
• A dependent variable is the variable being tested and measured in the experiment. The dependent variable is ‘dependent’ on the independent variable;
8
Lab 1 Report Tutorial: 2.0 Methodology 2.5 Data Analysis
• State what statistical procedures were used to analyze the data and identify the statistical software package used;
• Do not include any results in this section;
9
Lab 1 Report Tutorial: 3.0 Results
• Plot the class reaction time data using a Box-and-Whisker scatterplot;
• Note that you are permitted to use decimal for bits (as S/R 6 won’t yield a whole number)

12
Lab 1 Report Tutorial: 3.0 Results • Outliers
An outlier is any data point more than 1.5 interquartile ranges (IQRs) below the first quartile or above the third quartile.
Example:
For the data 2, 5, 6, 9, 12, we have the following five-number summary: • minimum = 2
• first quartile = 3.5
• median = 6
• third quartile = 10.5
• maximum = 12
IQR = 10.5 – 3.5 = 7, so 1.5·IQR = 10.5.
Bonus marks!

Lab 1 Report Tutorial: 3.0 Results Example:
For the data 2, 5, 6, 9, 12, we have the following five-number summary:
• minimum = 2
• first quartile = 3.5
• median = 6
• third quartile = 10.5
• maximum = 12
To determine if there are outliers we must consider the numbers that are 1.5·IQR or 10.5 beyond the quartiles.
• first quartile – 1.5·IQR = 3.5 – 10.5 = –7
• third quartile + 1.5·IQR = 10.5 + 10.5 = 21
Since none of the data are outside the interval from –7 to 21, there are no outliers.

Lab 1 Report Tutorial: 3.0 Results
• Calculate the average reaction time recorded for each of the S/R alternatives that were presented. Calculate the standard deviation, minimum, Q1, Median, Q3 and Maximum as well;

Lab 1 Report Tutorial: 3.0 Results
• Using the trendline function, plot a line of best fit. Ensure that you document the equation that best explains the your data and the amount of variance explained (R2).

Lab 1 Report Tutorial: 3.0 Results
Picture 3. A model with R-squared close to 1
R-squared can take value between 0 and 1 where values closer to 0 represent a poor fit while values closer to 1 represent a perfect fit .
How to interpret R-squared?
If R-squared=0.93 then it means 93% variations in dependent variable Y are explained by the independent variables present in our model.

Important Points
• All tables and pictures MUST be labeled;
• When you include a table or a picture, make sure you incorporate an introductory
paragraph for each one of them. I do not want to see only pictures and tables hanging around in this session.

Response Time
Lab 1 Report Tutorial: 4.0 Discussion This section should include but is not limited to:
Comment on the overall shape of the graph, as well as the variability (standard deviation magnitude) that exists across the class at each level we tested (1, 2, 4, 6, and 8 S/R pairs). Is this value consistent, or does it change as a function of the amount of information that was presented? Discuss the implications of this within your write up.
19
Lab 1 Report Tutorial: 4.0 Discussion This section should include but is not limited to:
• Discuss any practical design implications that might result from this experiment. Formulate 3-5 design principles based on the results of this experiment. Your design principles should all relate to the same field industry you could discuss training, lecturing in a classroom, software interfaces, or a field of your choice.
• What confidence do you have in the results?
• What are the limitations of the experiment?
20
Lab 1 Report Tutorial: 5.0 Conclusions
• Summarize the purpose, method, and results of this study. (Only present this
briefly.)
• Summarize significance of the findings.
• End with a statement on significance of this work. • Note: This part of the report is to say “Good Bye”.
21
Attention!
• You can use the software of your preference to analyze the data;
• You will get extra marks for analyzing outliers. The report is not about outliers, therefore, your efforts should not be concentrated here! A simple analysis is more than sufficient. Just make sure you are clear regarding the approach you took to deal with them.

References: Good Examples
In-text references should immediately follow the title, word, or phrase to which they are directly relevant, rather than appearing at the end of long clauses or sentences. In-text references should always precede punctuation marks. Below are examples of using in-text citation.
Author’s name in parentheses:
• One study found that the most important element in comprehending non-native speech is familiarity with the topic (Gass & Varonis, 1984).
