Tables in Research Reports
Tables are efficient tools used to present large amounts of data, such as means and standard deviations, particularly in complex research designs. A well-constructed table should be simple, self-interpretable, and focus on highlighting major trends rather than merely repeating statistical details that are already covered in the text.

What is the primary purpose of using descriptive statistics in psychological research?
Match each category of descriptive statistics with the specific goal it accomplishes when a researcher is summarizing their data.
A researcher finds that a distribution of scores on a memory task is negatively skewed, meaning there are a few extremely low scores that pull the tail of the distribution to the left. Arrange the following measures of central tendency in order from the lowest numerical value to the highest numerical value based on this distribution's shape.
In a psychological study where a distribution of scores is highly skewed by a single extreme outlier, the mean is a more valid descriptive statistic than the median for evaluating the typical performance of the sample.
Measures of dispersion, such as the standard deviation and variance, are descriptive statistics used to describe the average scores within a research sample.
Tables in Research Reports
A psychologist studies the sleep patterns of college students and wants to summarize the collected data. Why must the psychologist report both a measure of central tendency (such as the mean) and a measure of dispersion (such as the standard deviation) to provide a complete descriptive summary of the sample's sleep duration?
A researcher records the number of errors made by five participants on a memory task: 3, 8, 2, 5, and 7. The range for this sample is _____.
A research team is summarizing data from a psychology study. Match each descriptive statistic on the left to the research situation on the right where it would be the most appropriate single summary to report.
A researcher reports that two groups of participants completed an identical mood-rating scale (scored 0–100). Group A had a mean of 60 and a standard deviation of 4, while Group B had a mean of 60 and a standard deviation of 22. Although both groups share the same measure of central tendency, a student analyzing these results should conclude that Group B's scores show substantially greater _____ than Group A's scores.
A researcher has collected scores on a stress questionnaire from 80 undergraduate participants and must decide which descriptive statistics to select and report. Arrange the following evaluative steps in the order that best supports an accurate, justified statistical summary of the data.
Define descriptive statistics and identify the two primary categories of quantitative techniques described in the text, including the specific measures associated with each.
Based on the case context, decide how the researcher should apply descriptive statistics to describe their data. Explain the two different types of measures the researcher needs to calculate and specify what each type of measure will communicate about the sample's performance.
A psychological researcher reports that a sample of participants completed a stress assessment, resulting in a mean score of and a standard deviation of . Explain what these specific descriptive statistics indicate about the scores of the participants in this sample.

What is a primary characteristic of a well-constructed table in a research report?
A researcher is drafting the results section of their study. To create a well-constructed table, they should ensure that the table duplicates all the statistical details that are already discussed in the text paragraphs.
A researcher is finalizing the results section of an experiment on memory and is preparing a table to present the data. Match each action taken by the researcher to the specific principle of effective table construction it demonstrates.
A researcher is finalizing the Results section for a study with a complex factorial design. Arrange the following actions in the logical order that best facilitates a reader's ability to analyze data trends while adhering to principles of reporting efficiency and table construction.
A researcher is constructing a table to present results from a study examining the impact of 'Room Temperature' (Cool, Warm) and 'Task Complexity' (Easy, Medium, Hard) on 'Student Focus' (measured by Time on Task and Number of Errors). To synthesize these variables into a single, self-contained table that best highlights how Temperature and Complexity interact across both focus measures, which design should the researcher create?
A researcher studying memory creates a table to show recall scores across four conditions. However, they use the abbreviations 'CD1', 'CD2', 'CD3', and 'CD4' for the column headers without explaining them in the table, requiring the reader to search the rest of the report for their meaning. True or False: This table successfully follows the principle of being self-interpretable.
According to the guidelines for psychological research reports, in which context are tables considered particularly efficient tools for presenting summary data like means and standard deviations?
Match each characteristic of an effective research report table with its primary purpose or definition.
A researcher is finalizing a manuscript for a complex study and needs to present their data using an efficient, self-interpretable table. Arrange the following steps in the most logical order to transform a raw statistical output into a high-quality table that avoids redundant repetition.
In a research report, what is a key characteristic of a well-constructed table used to present data like means and standard deviations?
Formatting APA-Style Tables
A peer reviewer evaluates a Results section for a complex study and determines that a table presenting and values is poorly constructed because a reader cannot understand the data without referring back to the manuscript text to see what the labels in each row represent. This table fails to meet the evaluative criterion of being _____.
When critiquing a research report, a reviewer notes that a table is technically accurate but fails to provide a clear summary of the overall findings because it includes too much redundant detail. The reviewer should evaluate the table as poor because high-quality tables are intended to prioritize highlighting major _____.
