The Leaving Certificate Examination (Irish: Scrúdú na hArdteistiméireachta), commonly referred to as the Leaving Cert or (informally) the Leaving (Irish: Ardteist), is the final exam of the Irish secondary school system and the university matriculation examination in Ireland.
The new leaving certificate grading system involves grades such as H1, H2, O1, O2, etc. Leaving Certificate results are measured by the number of 'points' awarded to the student. It is usually the number of points awarded to the student that forms the basis for the student's acceptance or otherwise into a course of higher education (e.g. a ...
A modified version of MUSIC, denoted as Time-Reversal MUSIC (TR-MUSIC) has been recently applied to computational time-reversal imaging. [11] [12] MUSIC algorithm has also been implemented for fast detection of the DTMF frequencies (Dual-tone multi-frequency signaling) in the form of C library - libmusic [13] (including for MATLAB ...
Different music exam boards may have different grade levels for instruments and music theory. There are also music exams which do not follow the graded system, but have other designations. For instance, the Royal School of Church Music 's Voice for Life training scheme designates levels by color (White, Light Blue, Dark Blue, Red, Silver, Gold ...
¯ is the sample mean; σ 2 is the population variance; s n 2 is the biased sample variance (i.e., without Bessel's correction) s 2 is the unbiased sample variance (i.e., with Bessel's correction) The standard deviations will then be the square roots of the respective variances.
This algorithm can easily be adapted to compute the variance of a finite population: simply divide by n instead of n − 1 on the last line.. Because SumSq and (Sum×Sum)/n can be very similar numbers, cancellation can lead to the precision of the result to be much less than the inherent precision of the floating-point arithmetic used to perform the computation.
The sample mean and sample covariance are not robust statistics, meaning that they are sensitive to outliers. As robustness is often a desired trait, particularly in real-world applications, robust alternatives may prove desirable, notably quantile-based statistics such as the sample median for location, [4] and interquartile range (IQR) for ...
Most time signatures consist of two numerals, one stacked above the other: The lower numeral indicates the note value that the signature is counting. This number is always a power of 2 (unless the time signature is irrational), usually 2, 4 or 8, but less often 16 is also used, usually in Baroque music. 2 corresponds to the half note (minim), 4 to the quarter note (crotchet), 8 to the eighth ...
