This page contains sample papers formatted in seventh edition APA Style. The sample papers show the format that authors should use to submit a manuscript for publication in a professional journal and that students should use to submit a paper to an instructor for a course assignment. You can download the Word files to use as templates and edit them as needed for the purposes of your own papers.
The following two sample papers were published in annotated form in the Publication Manual and are reproduced here as PDFs for your ease of use. The annotations draw attention to content and formatting and provide the relevant sections of the Publication Manual (7th ed.) to consult for more information.
These sample papers demonstrate APA Style formatting standards for different student paper types. Students may write the same types of papers as professional authors (e.g., quantitative studies, literature reviews) or other types of papers for course assignments (e.g., reaction or response papers, discussion posts), dissertations, and theses.
NASA's Sample Retrieval Lander would touch down on Mars and remain in place to receive a diverse collection of scientifically curated samples of Martian rock already collected and cached by NASA's Perseverance rover.
Biggest Lander Ever Sent to Mars
The payload mass of the lander is double that of the Perseverance rover (1,241 pounds, or 563 kilograms). The lander's hefty cargo would include a rocket, sample transfer arm, and two helicopters. Each landing leg would be roughly the size of a human adult, with the whole lander standing about as tall as a professional basketball player.
First Mars Vehicle to Carry Two Helicopters
These aerial explorers would be based on the Ingenuity Helicopter carried to the Red Planet by the Perseverance rover. They would have wheels added for agility and a small arm to grab one sample tube at a time, in case the helicopters are needed to help retrieve Mars samples left by Perseverance.
Interactions with Multiple Vehicles
The lander would interact with the Perseverance rover, the Sample Recovery Helicopters (as needed), and the Mars Ascent Vehicle in order to prepare the sample tubes for launch into orbit around Mars. The task requires many highly accurate robotic arm movements, to be performed by ESA's Sample Transfer Arm.

New rules published on May 17, 2016, under the Americans with Disabilities Act (ADA) require employers that offer wellness programs that collect employee health information to provide a notice to employees informing them what information will be collected, how it will be used, who will receive it, and what will be done to keep it confidential. The EEOC has published the sample notice below to help employers comply with the ADA:

The proposed research will involve a small sample (less than 20 participants) recruited from clinical facilities in the New York City area with Williams syndrome. This rare craniofacial disorder is associated with distinguishing facial features. Even with the removal of all identifiers, we believe that it would be difficult if not impossible to protect the identities of subjects given the physical characteristics of subjects, the type of clinical data (including imaging) that we will be collecting, and the relatively restricted area from which we are recruiting subjects. Therefore, we are not planning to share the data.
If x has length 1, is numeric (in the sense ofis.numeric) and x >= 1, sampling viasample takes place from 1:x. Note that thisconvenience feature may lead to undesired behaviour when x isof varying length in calls such as sample(x). See the examples.
The optional prob argument can be used to give a vector ofweights for obtaining the elements of the vector being sampled. Theyneed not sum to one, but they should be non-negative and not all zero.If replace is true, Walker's alias method (Ripley, 1987) isused when there are more than 200 reasonably probable values: thisgives results incompatible with those from R < 2.2.0.
When data sampling is enabled, the query is not performed on all the data, but only on a certain fraction of data (sample). For example, if you need to calculate statistics for all the visits, it is enough to execute the query on the 1/10 fraction of all the visits and then multiply the result by 10.
In this example, the query is executed on a sample from 0.1 (10%) of data. Values of aggregate functions are not corrected automatically, so to get an approximate result, the value count() is manually multiplied by 10.
When using the SAMPLE n clause, you do not know which relative percent of data was processed. So you do not know the coefficient the aggregate functions should be multiplied by. Use the _sample_factor virtual column to get the approximate result.
The _sample_factor column contains relative coefficients that are calculated dynamically. This column is created automatically when you create a table with the specified sampling key. The usage examples of the _sample_factor column are shown below.
This sample ballot tool includes: All candidates in every upcoming election occurring within the 100 most-populated cities in the U.S., plus all federal and statewide elections, including ballot measures, nationwide. Additional local elections and ballot measures may also be included. Tribal elections are not included. Territorial elections are included.
Thank you for using Ballotpedia's sample ballot tool. We test the tool on an ongoing basis for accuracy. The note below discusses how we do that, and how you can help. (Click here to read about the Eight Quality Benchmarks for a Sample Ballot Lookup Tool.)
Ballotpedia regularly tests our sample ballot's accuracy by looking up addresses on both it and the official sample ballot and comparing the lookup results from both tools. We strive for our sample ballot tool to be 100% accurate. This means that, for offices within our coverage scope, a person's sample ballot results should include every election that will appear on their actual ballot. It should also include every candidate running in those elections, except write-ins. Finally, it should not contain errors such as misspelled names, inaccurate incumbency labels, or incorrect political party affiliations.
This will bring up a selector list of analyses. A particular dialog can also be run directly from the command line, if you know its name (can be discovered by browsing piface.jar with a zip file utility). For example, the two-sample t-test dialog may be run using
I need consulting help I am providing this software for free, but that does not obligate me to also answer substantive questions on power/sample size for your research project. If you need statistical advice on your research problem, you should contact a statistical consultant; and if you want expert advice, you should expect to pay for it. Most universities with statistics departments or statistics programs also offer a consulting service. If you think your research is important, then it is also important to get good advice on the statistical design and analysis (do this before you start collecting data).
Use power prospectively for planning future studies.
Software such as is provided on this website is useful for determining an appropriate sample size, or for evaluating a planned study to see if it is likely to yield useful information.
Many funding agencies require a power/sample-size section in grant proposals. Following the above guidelines is good for improving your chances of being funded. You will have established that you have thought through the scientific issues, that your procedures are sound, and that you have a defensible sample size based on realistic variance estimates and scientifically tenable effect-size goals.

Returns a new list containing elements from the population while leaving theoriginal population unchanged. The resulting list is in selection order so thatall sub-slices will also be valid random samples. This allows raffle winners(the sample) to be partitioned into grand prize and second place winners (thesubslices).

Often, a population is too large or extensive in order to measure every member and measuring each member would be expensive and time-consuming. A sample allows for inferences to be made about the population using statistical methods.
The laws of statistics imply that accurate measurements and assessments can be made about a population by using a sample. Analysis of variance (ANOVA), linear regression, and more advanced modeling techniques are valid because of the law of large numbers and the central limit theorem.
This will depend on the size of the population and the type of analysis you'd like to do (e.g., what confidence intervals you are using). Power analysis is a technique for mathematically evaluating the smallest sample size needed based on your needs. Another rule of thumb is that your sample should be large enough, but no more than 10% as large as the population.
Made chiefly of titanium, each sample tube weighs less than 2 ounces (57 grams). A white exterior coating guards against heating by the Sun potentially changing the chemical composition of the samples after Perseverance deposits the tubes on the surface of Mars. Laser-etched serial numbers on the exterior will help the team identify the tubes and their contents.
