A t-test can be used to account for the uncertainty in the sample variance when the sample size is small and the data are exactly normal. There is no universal constant at which the sample size is generally considered large enough to justify use of the plug-in test. Typical rules of thumb range from 20 to 50 samples. For larger sample sizes, the t-test procedure gives almost identical p-values as the Z-test procedure. Other location tests that can be performed as Z-tests are the two-sample location test and the paired difference test.
Definition of Caesura Literary Term. Caesura Literary Term is a grammatical pause or break in a line of poetry (like a question mark), usually near the middle of the line. A caesura is usually dictated by sense or natural speech rhythm rather than by metrics.
A poetic foot is a unit of accented and unaccented syllables that is repeated or used in sequence with others to form the meter. A caesura is a long pause in the middle of a line of poetry. To show an example of these symbols, let's look at a poem written with the less common, the accentual-syllabic meter, in mind.o get a bearing on what these rhythms look and sound like, let's start with a method for writing out the rhythms of a poem. This technique is called scansion, and it is important because it puts visual markers onto an otherwise entirely heard phenomenon.
