Tables
Tables enable the researcher to display a large amount of data
in a small amount of space. Data in tables are usually neatly displayed
in columns and rows. It is useful to include the right amount of tables
in an APA paper because 1) a reader may have difficulty sorting through many
tables and lose track of the message; 2) a disproportionately large number
of tables with a small amount of text can cause problems with the layout
of typeset pages; and 3) tables are more expensive to publish than text. Use
tables when the reader will find it difficult to interpret data in paragraph
form. Usually, it is a good idea to determine the amount of data the
reader needs to understand the discussion and then decide whether those data
are best presented in table or text form. Some guidelines to keep in
mind are:
Relation of Tables and Text:
Relation Between Tables:
- Identical columns or rows of data should not appear in two or more tables.
- Be consistent in how you present the tables.
- Use similar formats, titles, headings, and terminology.
Table Numbers:
- Use arabic numbers in the order in which the tables are mentioned in
the text.
- Do not use suffix letters to label tables.
- Ex: Do not use "Table 5, 5a, 5b..."
- Do not combine related tables into one table.
Table Titles:
- The title should be clear, explanatory, and brief.
- Ex: "Relation Between College Majors and Performance" (too telegraphic).
- Ex: "Mean Performance Scores on Test A, Test B, and Test C of Students
With Psychology, Physics, English, and Engineering Majors" (too detailed).
- Es: "Mean Performace Scores of Students With Different College Majors"
(good title).
- Do not use a specific footnote to clarify an element of the title.
Headings:
- Headings should be telegraphic and should not be many more characters than
the widest entry of the column it spans.
- Abbreviations of technical terms, group names, etc. must be explained in
a note to the table.
- Each column of a table must have a heading, even the leftmost column of
the table (called the stub column, which lists the major independent variables).
- To sobordinate within the stub, it is easier to indent stub items instead
of creating an additional column. Stubheads should be singular.
- A column head covers only one column. A column spanner covers two
or more columns, each with its own column head. Headings such as this
are called decked heads. Column spanners may be plural.
- Capitalize only the first letter of the first word of all haedings and
word entries.
Body of a Table:
- Decimal Values: Express numerical values in the number of decimal places
that the unit of measurement justifies. Do not change units of measurement
or the number of decimal places in a column.
- Empty Cells: Leave a cell blank if data are not applicable. Insert
a dash in the cell if the data were not obtained or are not reported.
- Do not include columns of data that can be calculated easily from other
columns.
Specific Types of Tables:
- Analysis of Variance (ANOVA) Tables
- Regression Tables
- Path and LISREL (linear structural relations) Tables
- Word Tables
Notes to a Table: Placed below the table.
- General Note: Explains information relating to the
table as a whole and ends with an explanaiton of abbreviations, symbols,
etc.
- Specific Note: Refers to a particular column, row, or individual entry. They
are indicated by superscript lowercase letters.
- Probability Note: Indicates the results of tests of significance. Asterisks
indicate values for which the null hypothesis is rejected, with the p value
specified in the probability note. Assign the same number of asterisks
from table to table within the paper. To distinguish between one-tailed and
two-tailed tests, use asterisks for the two-tailed p values and
alternate symols for the one-tailed p values.
- Order the notes to a table in the following order: general note, specific
note, probability note. The notes should be double-spaced and there should
be no paragraph indentation on the new line below the table.
Other things to keep in mind:
- Use horizontal rather than vertical rules.
- Design a table to fit the width of a journal page. If the count of characters
exceeds 60, the table will most likely not fit on a journal page.
- You must obtain permission to reproduce or adapt all or part of a table
from a copyrighted source. Any reproduced table must be accompanied by a
note at the bottom of the table giving credit to the original author and
copyright holder.
