Does the following word need a tilde on the accent? If so, what letter should have a tilde? "proposito"
Remember that only vowels (a,e,i,o,u) can have tildes. Tildes are placed in the accent or stressed syllable. Whether or not a word needs a tilde is dictated by the location of the accent and the letter that the word ends in (vowel, n, or s). This word is an esdrújula, which means that the third from the last syllable is stressed. In this case, words that are categorized as esdrújulas always have a tilde. The word should be written as such: propósito.
Are there any APA style errors in this excerpt? If so, please indicate them and how they should be corrected: "A study conducted by Peyton and Jackson showed that individuals were more likely to demonstrate improved test results after studying by themselves for thirty minutes before the test, 2017. However, another study demonstrated better test results when individuals studied for only ten minutes before the test (Patty Dell and Micheals 2008)."
There are five APA style errors in this excerpt. The first one is in the first sentence. When citing sources in a sentence, remember to keep the year of publication in parenthesis and immediately following the author's last name (after the name of the last author, if more than one). The sentence should read: "A study conducted by Peyton and Jackson (2017)...". The last of the errors are in the second sentence. When including a parentheses citation at the end of a sentence and there are two authors, only the author's last names should be included in the parenthesis and should be separated by an ampersand symbol. There should also be a comma after the name of the last author that separates the names from the year. The citation should read: (Dell & Micheals, 2008).
In your own words, describe what does reliability and validity refer to in a study. Think about how they are different and what each other of them offers to the quality of the study.
Remember that determining both the reliability and validity in a study helps to determine how effective a method is at measuring something. Reliability refers to consistency. When a method is reliable, it will continuously yield the same results, no matter how many times you measure a variable. For example, if you use a scale to determine the weight of a bag of oranges and the scale consistently reads the same weight every time you weigh it, the scale is reliable. Validity refers to accuracy. When a method is valid, it will measure a variable accurately. For example, if you place a 5lb bag of oranges on a scale and it reads its weight as 5lbs, then the scale is valid. Remember: reliability=consistency, validity=accuracy, or "RCVA"
