It is a characteristic or a quantity of interest that can take on different values, also known as?

Answer 5

Variable

Question 6

What are the 2 Categories of Data?

Answer 6

1. Categorical Data
2. Numerical or Continuous Data

Question 7

It is where arithmetic operation cannot be performed are nominal and ordinal scales; use non parametric statistics.

Answer 7

Categorical Data

Question 8

It consists of a finite sets of possible values having no particular order.
Ex. gender, mode of transportation, nationality, occupation, civil status.

Answer 8

Nominal Scales

Question 9

It is a set of possible values having specific order:
Ex. pain level, social status, attitude toward a subject.

Answer 9

Ordinal Scales

Question 10

It is numeric and arithmetic operation can be perform; ratio and interval scales; use parametric statistics.

Answer 10

Numerical or Continuous Data

Question 11

These are measured on continuum and differences between any two numbers of known size: temperature, tons of garbage, number of arrest, income and age.

Answer 11

Interval Scales

Question 12

These are numerical in nature and meaningful arithmetic can be done; age, weekly allowance, income of parents.

Answer 12

Quantitative Data

Question 13

It assumes exact value only and can be obtained by counting
Ex. number of students

Answer 13

Discrete Data

Question 14

It assumes infinite values within a specified interval and can be obtained by measurement
Ex. height

Answer 14

Continuous Data

Question 15

These are attributes which cannot be subjected to meaningful arithmetic.
Ex. gender

Answer 15

Qualitative Data

Question 16

It is where the data can be categorized in several ways based on how they are collected and the type collected.

Answer 16

Population and Sample Data

Question 17

It is not feasible to collect data from the population of all elements of interest. In such instances, we collect data from a subset of the population known as?

Answer 17

Sample / Sample Data

Question 18

These data are collected from several entities at the same, or approximately the same, point in time.

Answer 18

Cross-Sectional Data

Question 19

These are the data collected over several time periods. Graphs of data are frequently found in business and economic publications. Such graphs help analysts understand what happened in the past, identify trends over time, and project future levels for the time series.

Answer 19

Time Series Data

Question 20

It is where a variable of interest is first identified. Then one or more other variables are identified and controlled or manipulated so that data can be obtained about how they influence the variable of interest.

Answer 20

Experimental Study

Question 21

The studies make no attempt to control the variables of interest. A survey is perhaps the most common type of observational study.

Answer 21

Non-experimental or Observational

Question 22

This is where the data gathered shall be presented; analyzed and interpreted that can be easily understood by the reader.

Answer 22

Presentation of Data

Question 23

It is presented in paragraph or in sentences are said to be in textual form.

Answer 23

Textual Data

Question 24

It uses statements with numerals in order to describe the data for the concrete information and in expository form. It is to discuss the data and the information and interpretation it carries.

Answer 24

Textual Presentation

Question 25

This is a table which shows data arrange into different classes, and the number of cases which fall into each class.

Answer 25

The Frequency Distribution Table

Question 26

It uses statistical table to directly display the quantities or values collected as data.

Answer 26

Tabular Presentation

Question 27

It adds life and beauty to one’s work, but more than this, it helps facilitate comparisons and interpretation without giving through the numerical data. These are devices that help minimize the “thinking through” process as one analyzes statistical or quantitative data.

Answer 27

Graphs / Graphical

Question 28

It illustrates data in a form of a graph, aiding readers to understand the text easily, A graph is the most attractive, effective and convincing way. There are various types of graphs we can prepare like bar graph, line graph and pictograph.

Answer 28

Graphical Presentation

Question 29

It represents by either vertical or rectangular rectangles whose bases represent the class intervals, and whose height represents the frequencies, It is used for discrete variables.

Answer 29

Bar Chart

Question 30

It is a circle graph showing the proportion of each class, through the relative or percentage frequencies. Legends are used to provide a clearer distinction of categories and types (of business firms for example). Graphs complement the tabular presentation of data.

Answer 30

Pie Chart

Question 31

It is a type of chart used to show information that changes over time. These are created by plotting a series of several points and connecting them with a straight line, and used to track changes over short and long periods.

Answer 31

Line Chart

Question 32

It is where a grouping of the data into categories showing the number of observations in each of the non-overlapping classes.

Answer 32

Frequency Distribution

Question 33

It refers to the data gathered where it should be properly organized in to grouped data called frequency distribution.

Answer 33

Grouped Data

Question 34

It can be used to provide estimates of the relative likelihoods of different values of a random variable.

Answer 34

Percent Frequency Distribution

Question 35

It is a tabular summary of data showing the relative frequency for each bin.

Answer 35

Relative Frequency Distribution

Question 36

It refers to a graph in which the classes are marked on the horizontal axis (x axis ) and the class frequencies on the vertical axis (y axis). It focusses on the frequency for each class and sacrifices whatever information is contained in the actual observation.

Answer 36

Histogram

Question 37

It is a graph that displays the data using points which are connected by lines. The frequencies are represented by the heights of the points at the midpoint of the classes.

Answer 37
