Communism. only one group has a say
Answer:
A) The greater the variance within the population, the larger the sample should be.
Explanation:
The variance of a sample mean is inversely proportional to the sample size, that is, the larger the sample size the smaller the variability of the sample. When sample size increases, the range decreases and hence the variance decreases resulting in a more accurate research result with minimal experimental error.
Hence the researcher should employ a large sample size to reduce the variation in the population.
Answer:
a) a mnemonic device
Explanation:
A mnemonic device is a learning technique that helps to encode information and to remember it.
Mnemonic device use <u>retrieval cues, imagery, songs, rhyme, acronyms, sentences</u>. All of these are used to help the original information to become associated with something more meaningful.
In this example, Tim <u>needs to remember the spelling of "geography" so he learns a sentence that serves as an acronym</u> (since the first letter of each word correspond with each letter of the word he needs to learn), so he's using a cue, in this case an acronym or sentence so <u>he can associate the spelling (original information) with something more meaningful to him </u>(the creative sentence of George)
Thus, the correct answer is a) a mnemonic device.
