# What is an example of a discrete graph?

## What is an example of a discrete graph?

Discrete functions are used for things that can be counted. For example, the number of televisions or the number of puppies born. The graph of discrete functions is usually a scatter plot with scattered points like the one you just saw.

## What is a discrete graph in math?

Graph: A discrete graph is a series of unconnected points (a scatter plot). Domain: a set of input values consisting of all numbers in an interval. Domain: a set of input values consisting of only certain numbers in an interval.

## What is a discrete relationship?

A discrete function is a function with distinct and separate values. This means that the values of the functions are not connected with each other. For example, a discrete function can equal 1 or 2 but not 1.5.

## What is discrete data in research?

Definition of Discrete Data: Information that can be categorized into a classification. Discrete data is based on counts. Only a finite number of values is possible, and the values cannot be subdivided meaningfully. It is typically things counted in whole numbers.

## Is age continuous or discrete?

Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. For example, someone could be years old or years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.

## What is discrete series example?

Discrete series means where frequencies of a variable are given but the variable is without class intervals. Here the mean can be found by Three Methods. (i) Direct Method: ADVERTISEMENTS: Here each frequency is multiplied by the variable, taking the total and dividing total by total number of frequencies, we get X.

## What is N in discrete series?

Mathematically, Mean is given by the equation: Mean = ∑ xi/ n { xi : All values of x from 1 to n; n: Total number of observations} The mean of values in our example is calculated as follows: Mean = ∑ (250+ 300 + 350 +300 +400)/ 5.

## How do you write a discrete series?

If we are to prepare discrete series from individual series or raw data, it is better to place values in ascending order, then against these variables we put tally bar for each item against the corresponding variable, then number of total tally bars is counted and a numerical number is put in 3rd column as frequency.

## How do you find the mean deviation in a discrete series?

For discrete series, the Mean Deviation can be calculated using the following formula….FormulaN = Number of observations.f = Different values of frequency f.x = Different values of items.Me = Median.

## How mean deviation is calculated?

Mean deviation is a statistical measure of the average deviation of values from the mean in a sample. It is calculated first by finding the average of the observations. Find the average of these values by adding them and then and dividing them by the number of values.

## How can we find mean deviation?

Mean DeviationFind the mean of all values.Find the distance of each value from that mean (subtract the mean from each value, ignore minus signs)Then find the mean of those distances.

## What is a continuous series?

Continuous series means where frequencies are given along with the value of the variable in the form of class intervals. For example. Here: are class intervals. (ii) 3, 7, 11, 9, 6 is known as their respective frequencies.

## What are the types of continuous series?

Explain the different types of continuous series.Exclusive series- Series in which every class interval excludes items corresponding to its upper limit.Inclusive series- Series which includes all items up to its upper limit.Open end series- Series in which lower limit of the first class interval and / or the upper limit of last class interval is missing.

## Can mode be applied to continuous data?

Grouped variables (continuous or discrete) This is called the modal-class interval. The mode can be used with categorical data, but the mean and median cannot. The mode may or may not exist, and there may be more than one value for the mode.

## How do you find the continuous series?

In case of continous series, a mid point is computed as lower−limit+upper−limit2 and Arithmetic Mean is computed using following formula….N = Number of observations.f1,f2,f3,…,fn = Different values of frequency f.m1,m2,m3,…,mn = Different values of mid points for ranges.

## How do you find a sample mean?

The following steps will show you how to calculate the sample mean of a data set:Add up the sample items.Divide sum by the number of samples.The result is the mean.Use the mean to find the variance.Use the variance to find the standard deviation.

## What is class interval?

The class intervals are the subsets into which the data is grouped. The width of the class intervals will be a compromise between having intervals short enough so that not all of the observations fall in the same interval, but long enough so that you do not end up with only one observation per interval.

## What is the lowest class interval?

The lowest number in a class interval is called the lower limit and the highest number is called the upper limit. This example is a case of continuous class intervals as the upper limit of one class is the lower limit of the following class.

## What is class interval example?

The range of each group of data. Example: you measure the length of leaves on a rose bush. Some are less than 1 cm, and the longest is 9 cm.
