Class intervals were determined using the Spiegel equation: CI = A/NC, where A = amplitude, NC (number of classes) = 1 + 3.3 log (n) and n = number of individuals (Felfili, 1995).
Majority of the CIMT<0.9 mm group patients belonged to the male gender
class interval (n=5, 50%).
Using the 'narrow' interval, the probability of success (observed value falling within the
class interval) fell to 36%.
The data illustrated that frequency of access across the various
class intervals, of podcasts was not equitably distributed during both years.
The reduced data set with n = 289 was divided to k = 9 intervals according to the (5) formula and as the outliers testing gave us a data set whose values vary in the range of <0; 0.19>, we will get the h = 0.02 width of the
class interval by fractioning the highest value by the k parameter and by rounding the result to centimetres.
Unlike the Poisson distribution which is discrete distribution considering the counts of vehicles, a negative exponential model is a continuous curve taking into account frequency
class interval. It describes times between events in the Poisson process and can be derived from the equation of probability mass function for Poisson.
Studies were divided into three
class intervals (ie, three groups of studies of different levels of 'quality,' low, medium and high).
Use a
class interval of size $2,500 to form a frequency distribution for the data.
Efficiency improvements to the estimator, by Bakker (1997), demonstrated that to use equation (6) in a frequency context it is necessary to divide the density's domain into K
class intervals, such that the probability associated with the kth
class interval is:
At each
class interval, 150 oysters were sampled without replacement.
Majority of the hypothyroid Group patients belonged to the 31-40 years age
class interval (n=13, 35.14%) with a mean age of 35.37 years.
The tables in this publication include data on the number of staff employed in Title IV postsecondary institutions in fall 2006 by primary occupational activity, length of contract/teaching period, employment status, salary
class interval, faculty and tenure status, academic rank, race/ethnicity, and gender.
