It is useful to compare the standard error of the mean for the age of the runners versus the age at first marriage, as in the graph. Roman Letters b = y intercept of a line. Small ι, ο and υ are also rarely used, since they closely resemble the Latin letters i, o and u.

Symbol For Population Standard Deviation Simple Linear Regression Β0 is the intercept constant in a population regression line. Β1 is the regression coefficient (i.e., slope) in a population regression line. Mean Symbol In Word g(x; P) refers to geometric probability.

The Bayer designation naming scheme for stars typically uses the first Greek letter, α, for the brightest star in each constellation, and runs through the alphabet before switching to Latin letters.

nPr refers to the number of permutations of n things taken r at a time. Defined **here in Chapter2.** The proportion or the mean is calculated using the sample. Check This Out The standard error of the mean (SEM) can be seen to depict the relationship between the dispersion of individual observations around the population mean (the standard deviation), and the dispersion of

For each sample, the mean age of the 16 runners in the sample can be calculated. Numeral[edit] σ' The number 200 in Greek numerals. ,σ The number 200,000 in Greek numerals. http://cpresourcesllc.com/standard-deviation/standard-error-n-or-n-1.php These assumptions may be approximately met when the population from which samples are taken is normally distributed, or when the sample size is sufficiently large to rely on the Central Limit

x (lower-case x) = one data value ("raw score"). Defined here in Chapter4. (The TI-83 uses a and some statistics books use b1.) M or Med = median of a sample. SEP = standard error of the proportion (symbol is σp̂). CI = confidence interval.

R² = coefficient of determination. Defined here in Chapter5. d = difference between paired data. Student approximation when σ value is unknown[edit] Further information: Student's t-distribution §Confidence intervals In many practical applications, the true value of σ is unknown.

DPD = discrete probability distribution. Note: The Student's probability distribution is a good approximation of the Gaussian when the sample size is over 100. In fact, data organizations often set reliability standards that their data must reach before publication. Capitalization In general, capital letters refer to population attributes (i.e., parameters); and lower-case letters refer to sample attributes (i.e., statistics).

For example, μ refers to a population mean; and x, to a sample mean. σ refers to the standard deviation of a population; and s, to the standard deviation of a Defined here in Chapter10.
