An array of frequencies according to variate values, which is called the frequency distribution.

A Frequency array is an array of frequencies according to variate values, that is to say, a frequency distribution. The term “array” is often used for the individual frequency distributions which form the separate rows and columns of a bivariate frequency.

A Frequency Curve is a smooth curve which corresponds to the limiting case of a histogram computed for a frequency distribution of a continuous distribution as the number of data points becomes very large.

A two-way table is associated with two variables, say X and Y. In other words, a bivariate frequency distribution is the frequency distribution of two variables. Table 3.17 shows the frequency distribution of two variables, namely, age and marks obtained by 50 students in an intelligent test.

A non-distributed array is one in which the whole array resides in a worker’s memory space while a distributed array is a single array with its parts distributed across workers in a specific fashion. …

There are different types of frequency distributions.

• Grouped frequency distribution.
• Ungrouped frequency distribution.
• Cumulative frequency distribution.
• Relative frequency distribution.
• Relative cumulative frequency distribution.

The 3 types of frequency distributions are:

• Ungrouped Frequency Distribution.
• Grouped Frequency Distribution.
• Relative Frequency Distribution.

[6] They are as follows: Measures of central tendency and location (mean, median, mode) Measures of dispersion (range, variance, standard deviation) The extent of symmetry/asymmetry (skewness)

The frequency table is a tabular form in which each piece of data is assigned to its corresponding frequency while a frequency distribution is the graphical representation of a frequency table.

In statistics, a frequency distribution is a list, table or graph that displays the frequency of various outcomes in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval.

Class frequency refers to the number of observations in each class; n represents the total number of observations in the entire data set. For the supermarket example, the total number of observations is 200. The relative frequency may be expressed as a proportion (fraction) of the total or as a percentage of the total.

A normal frequency distribution is a theoretical continuous, symmetrical, bell-shaped distribution function. Its mean, mode and median are all the same; and both the tails of the bell curve are infinitely long. Simple normal distributions are frequently used for modelling uncertainty.

Steps to Making Your Frequency Distribution

1. Step 1: Calculate the range of the data set.
2. Step 2: Divide the range by the number of groups you want and then round up.
3. Step 3: Use the class width to create your groups.
4. Step 4: Find the frequency for each group.

Example 1 – Constructing a frequency distribution table

1. Divide the results (x) into intervals, and then count the number of results in each interval.
2. Make a table with separate columns for the interval numbers (the number of cars per household), the tallied results, and the frequency of results in each interval.
