## What is the meaning of frequency and examples?

Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. For example, an “A” note on a violin string vibrates at about 440 Hz (440 vibrations per second).

## What are the characteristics of frequency?

There are four important characteristics of frequency distribution….CHARACTERISTICS OF FREQUENCY DISTRIBUTION

- 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 difference between frequency table and frequency distribution?

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.

## Do all objects have a frequency?

All objects have a natural frequency or set of frequencies at which they vibrate. Still other objects will vibrate at a set of multiple frequencies that have no simple mathematical relationship between them.

## What is a frequency table with intervals?

A frequency table organizes the data in three columns by displaying the intervals, a tally of the number of values within the interval, and a numerical value of the tally. A tally is a mark made to keep count of the number of values within the interval.

## How do you find the mode in a frequency table?

How To Obtain The Mean, Median And Mode From A Frequency Table? To find the mean: Multiply midpoints by frequencies, add the subtotals and divide by the total of the frequencies. To find the mode: Look for the largest frequency and the corresponding value is the modal value or modal class.

## How do you make a continuous frequency table?

Steps used to construct Frequency distribution continuous

- Find the maximum and minimum value from the given data.
- Decide the number of classes to be formed.
- Find the difference between the maximum and minimum value and divide this difference by the number of classes to be formed to determine the class interval.

## How do you form a continuous class interval?

Answer Expert Verified In order to make class intervals continuous, you are supposed to subtract 0.5 from the lower limit and add 0.5 in the upper limit.

## Is age discrete or continuous?

We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous. However, in everyday appliances, all values under 6 years and above 5 years are called 5 years old. So we use age usually as a discrete variable.

## How do you convert a frequency distribution to a continuous grouped frequency table?

1 Answer

- Consider the classes 150 – 153 and 154 – 157.
- The lower limit of 154 – 157 = 154.
- The upper limit of 150 – 153 = 153.
- The difference = 154 – 153 = 1.
- Half the difference = 1/2 = 0.5.
- So, the new class interval formed from 150 – 153 is (150 – 0.5) – (153 + 0.5), i.e., 149.5 – 153.5.
