Frequency distribution is an important tool in statistics that allows you to present the characteristics of variables in the form of a table or histogram. This allows you to see the quantitative relationship of the values, regardless of what measurements were taken.
One example where frequency distribution can be useful is in analyzing physiological parameters of people, such as their height, weight, or blood pressure. In such cases, a frequency distribution can help the researcher understand how given parameters are distributed in the sample and which values occur most frequently.
In a normal (or Gaussian) distribution, the values and their range on each side of the underlying value have symmetry. This means that the values move evenly to either side of the mean, and there are approximately equal numbers of values to the left and right of the mean.
However, with a skewed distribution (such as a Poisson distribution), the resulting values skew toward one side of the underlying value and extend a significant distance toward the other side. In such cases, frequency distribution can help researchers see how data is distributed in a sample and highlight the most significant values.
The frequency distribution can be presented in the form of a table or a histogram. In the table, each variable value is presented along with its frequency value in the sample. In a histogram, the values of a variable are divided into intervals, and the height of each histogram column corresponds to the number of values that fall within that interval.
In conclusion, frequency distribution is an important tool in statistics that allows researchers to understand how data is distributed in a sample. It can be presented as a table or bar graph, and is used to analyze various variables such as height, weight or blood pressure. It is important to consider that with a skewed distribution, data may be biased to one side of the underlying value, and the frequency of the distribution can help researchers isolate the most significant values.
Frequency Distribution is a representation of the characteristics of some physiological parameter, such as height, weight, or blood pressure, in the form of a table or histogram. This makes it possible to reflect their quantitative relationships despite different measurements.
In statistics, under a normal or Gaussian distribution, the number of values and range on each side of the underlying value are symmetrical. With an asymmetric distribution, such as Poisson, the values are grouped on one side of the main value, and on the other side they are spread out at a considerable distance from it.
Frequency distribution
In statistics, frequency distribution represents the characteristics of certain physiological (height, weight) parameters of people in the form of tables or histograms. This is often done in such a way as to reflect a quantitative relationship regardless of different measurements. The main purpose of frequency distribution is to
