Which of the following is an example of discrete data?

Which of the following is an example of discrete data?

Examples of discrete data include the number of people in a class, test questions answered correctly, and home runs hit. Tables, or information displayed in columns and rows, and graphs, or structured diagrams that display the relationship among variables using two axes, are two ways to display discrete data.

What is the formula of discrete series?

The mean of discrete series is obtained by simply adding up all the observations and then dividing the sum by the total number of observations.

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 display discrete data?

1. Column Charts. The most commonly used chart type for discrete data is the column chart.
2. Bar Charts. You also can use bar charts for discrete values.
3. Pie Charts. Pie charts also work well for displaying discrete data, as all the values combined equal 100 percent of the total.
4. Histograms.

What is a discrete frequency table?

Discrete data is generated by counting, and each and every observation is exact. The number for which the observation is repeated is called the frequency of that observation. The class limits in discrete data are true class limits; there are no class boundaries in discrete data.

Is time continuous or discrete?

Time is a continuous variable. You could turn age into a discrete variable and then you could count it. For example: A person’s age in years.

How do you know if a variable is discrete or continuous?

A variable is a quantity whose value changes. A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. A random variable is a variable whose value is a numerical outcome of a random phenomenon.

Is time a discrete variable?

Discrete time views values of variables as occurring at distinct, separate “points in time”, or equivalently as being unchanged throughout each non-zero region of time (“time period”)—that is, time is viewed as a discrete variable.

What variable is height?

Continuous variables Examples of a continuous variable are distance, age and temperature. The measurement of a continuous variable is restricted by the methods used, or by the accuracy of the measuring instruments. For example, the height of a student is a continuous variable because a student may be 1…

Is height a dependent variable?

the average height of adults might give you a graph as shown below. The independent variable is average height. The dependent variable is weight. For example, height might be an independent variable in the context stated above but a dependent variable in a study on the effect of nutrition on growth rates.

What are the 5 variables?

There are six common variable types:

• DEPENDENT VARIABLES.
• INDEPENDENT VARIABLES.
• INTERVENING VARIABLES.
• MODERATOR VARIABLES.
• CONTROL VARIABLES.
• EXTRANEOUS VARIABLES.

What are 3 control variables?

An experiment usually has three kinds of variables: independent, dependent, and controlled.

What are the 4 types of variables?

Four Types of Variables You can see there are four different types of measurement scales (nominal, ordinal, interval and ratio). Each of the four scales, respectively, typically provides more information about the variables being measured than those preceding it.
