# Characteristics of Frequency Distribution In Nigeria

Measures of central tendency and location (mean, median, mode) Measures of dispersion (range, variance, standard deviation) The extent of symmetry/asymmetry (skewness) The flatness or peakedness (kurtosis).

## What is the importance of frequency distribution?

The importance of frequency distributions in statistics is great. A well-constructed frequency distribution makes possible a detailed analysis of the structure of the population with respect to a given characteristic. Thus, the groups into which the population breaks down can be determined.

## What is the concept of frequency distribution?

frequency distribution, in statistics, a graph or data set organized to show the frequency of occurrence of each possible outcome of a repeatable event observed many times. Simple examples are election returns and test scores listed by percentile. A frequency distribution can be graphed as a histogram or pie chart.

## What are the 3 types of frequency distributions?

**3 types of frequency distributions**are: Ungrouped

**Frequency Distribution**. Grouped

**Frequency Distribution**. Relative

**Frequency Distribution**.

## What are the essential parts of a frequency distribution?

**components**of the

**frequency distribution**are: Class interval, types of class interval, class boundaries, midpoint or class mark, width or size o class interval, class

**frequency**,

**frequency**density = class

**frequency**/ class width, relative

**frequency**= class

**frequency**/ total

**frequency**, etc.

## What is the importance of frequency distribution table?

**frequency distribution table**can help you organize this data to find out. A

**frequency distribution table**is a chart that summarizes values and their

**frequency**. It’s a useful way to organize data if you have a list of numbers that represent the

**frequency**of a certain outcome in a sample.

## What do you mean by frequency distribution?

**frequency distribution**is a representation, either in a graphical or tabular format, that displays the number of observations within a given interval. The intervals must be mutually exclusive and exhaustive.

**Frequency distributions**are typically used within a statistical context.

## What is the formula of frequency distribution?

**frequency distribution formula**is as follows: Divide the number of categories/values into intervals, then count the number of results in each interval. These number of times or occurrences represent

**frequency**.

## What is the function of frequency?

**FREQUENCY function**calculates how often values occur within a range of values, and then returns a vertical array of numbers. For example, use

**FREQUENCY**to count the number of test scores that fall within ranges of scores.

## What is the define of frequency?

**Frequency**, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.

## What are the two arguments for the frequency function?

**The FREQUENCY function has two arguments:**

- data_array – a range of cells containing numeric values.
- bins_array –a range of cells containing bins into which the numeric values should be grouped.

## How do you use the frequency function?

**To create a frequency distribution using FREQUENCY:**

- Enter numbers that represent the bins you want to group values into.
- Make a selection the same size as the range that contains bins, or one greater if want to include the extra item.
- Enter the
**FREQUENCY function**as an array formula using control+shift+enter.

## How do u find the frequency?

**How to calculate frequency**

**Determine**the action. Decide what action you want to use to**determine**the**frequency**.- Select the length of time. Select the length of time over which you will measure the
**frequency**. - Divide the numbers. To
**calculate frequency**, divide the number of times the event occurs by the length of time.

## How do you find absolute frequency?

**absolute frequency**is the number of times that a certain value appears in a statistical study. It is denoted by f

_{i}. The sum of the

**absolute frequencies**is equal to the total number of data, which is denoted by N. This sum is commonly denoted by the Greek letter Σ (capital sigma) which represents ‘sum’.

## What is the sum of all frequencies?

**sum of all**the

**frequencies**for

**all**classes is equal to the number of elements in the given data and that

**summation**is termed as the cumulative

**frequency**which defines the number of entries of that statistical data.

## What is frequency example?

**Frequency**is the number of occurrences of a repeating event per unit of time. For

**example**: if a newborn baby’s heart beats at a

**frequency**of 120 times a minute (2 hertz), its period, T—the time interval between beats—is half a second (60 seconds divided by 120 beats).

## What is the absolute frequency?

**Absolute frequency**is a statistical term describing the number of times a particular piece of data or a particular value appears during a trial or set of trials. Essentially,

**absolute frequency**is a simple count of the number of times a value is observed.

## What is the difference between a frequency and a relative frequency?

**difference between frequency**and

**relative frequency**is that

**frequency**relies on the actual values of each class

**in a**statistical data set while

**relative frequency**compares these individual values to the overall totals of all classes concerned

**in a**data set.

## What does frequency mean in a frequency table?

**Frequency**refers to the number of times an event or a value occurs. A

**frequency table**is a

**table**that lists items and shows the number of times the items occur. We

**represent**the

**frequency**by the English alphabet ‘f’. For example, Alan has to put the footballs in two boxes.

## What is the difference between absolute frequency and relative frequency?

**frequency**(or

**absolute frequency**) of an event is the number of times the event occurred

**in an**experiment or study. The

**relative frequency**(or empirical probability) of an event refers to the

**absolute frequency**normalized by the total number of events.

## What are the characteristics of frequency polygon?

The frequency polygon is a curve that is drawn on the x-axis and the y-axis. The x-axis represents the values in the dataset, while the y-axis shows the number of occurrences of each distinct category. The frequency polygon can serve as an alternative to a histogram.
