is one that can be answered by collecting data that vary.

(a)  

what are the two types of data?

(a)  

those in numerical form which are either continuous or discrete

(a)  

2 forms of numerical data set

(a)  

are those that can be counted in a finitely (means in a way that has a limit or end.)

(a)  

are measurements

that can take any value from an is infinite range

(a)  

take non-

numerical values, such as colors, information or questions that are answerable by

YES or NO, labels, etc (example: large, medium, and small)

(a)  

The 4 steps below can be followed to solve real life problems using statistics

(a)  

There are different statistical instruments that can be formulated and used to

gather data depending on the needs. what are some of the statistical

instruments.

(a)  

it focuses in determining the changes in the attitude, characteristics

and behavior of people or other subjects. This technique includes watching and

recording actions and behaviours

(a)  

it is being performed through personally asking questions to people

who have the authority or expertise to say something about the data needed.

The person gathering the data is called the interviewer, while the person supplying

the data is the interviewee.

(a)  

it is used to know the thinking, feeling or

opinion, about a certain phenomenon, idea and etc. it is conducted with a small

group of people with common knowledge and common field (usually 6 to 8 people).

(a)  

on this method data is gathered through a set of questions that is mailed or handed to respondents who are expected to read them

(a)  

to determine the cause and effect relationship of a certain phenomenon

(a)  

what are the Types of Questions

(a)  

These are questions which can be answered with “Yes” or “No,” or they have a

limited set of possible answers

(a)  

These are questions that allow someone to give a free-form answer. Example,

“How did you answer the modules?”

(a)  

These are questions that provide a certain number of specific response options

as possible answers. An example of multiple-choice question would be:

“How do you spend your free time?”.

a. reading c. surfing the internet

b. listening to radio d. watching TV e. others (please specify: (a)   )

in a national level, surveys are usually covered by the government and

other form of surveying organization such as National Statistics Office

Methods Used in the Collecting Data

(a)  

this method of collecting data is an oral or verbal

communication where the interviewer asks questions in any mode to an interviewee. The person gathering the data

is called the interviewer, while the person supplying the data is the

interviewee.

(a)  

The person gathering the data

(a)  

the person supplying the data

(a)  

on this method data is gathered through a set of

question that is mailed or handed to respondents who are expected to read

and understand them. And the respondents then, write down their

responses in the space provided the accomplished questionnaire is then

returned for appropriate processing.

(a)  

the data on this method are gathered either

individually or collectively by means of observation. The person who gathers

the data is called an investigator while the person being observed is called

the subjec

(a)  

The person who gathers

the data for observation method

(a)  

person being observed in an observation method

(a)  

this method is used when the objective is to

determine the cause and effect relationship of a certain phenomenon under

controlled condition

(a)  

the next step after gathering data

(a)  

the number of occurrences of a data

(a)  

is a table that lists items and shows the number of

times the items occur.

(a)  

When data are presented as graph, they are easily interpreted, and compared. As a

consequence, data become more interesting to the readers

(a)  

can be presented graphically to give a

better picture of the distribution. Some forms of graphs pie chart, bar graph and line graph.

(a)  

is a visual representation of data. It is used to show

how all the parts of something are related to the whole. It is represented by a circle

divided into slices or sectors of various sizes that show each part’s relationship to

the whole and to other parts of the circle.

(a)  

uses rectangles (or bars) of uniform width to represent data,

particularly the nominal or categorical type of data. The height of the rectangle

denotes the frequency of the variable

(a)  

two types of bar graph

(a)  

is used to represent changes in data over a period of time. Data like

changes in temperature, income, population, and the like can be represented by a

line graph.

(a)  

2 forms of graphs for grouped frequency distribution

(a)  

shows the frequency of data that occur within a

certain interval, the bars are always vertical, the width of each bar

is based upon the size of the interval it represents, and there are no gaps between

adjacent bars it has no gaps because their bases cover a continuous

range of possible values.

(a)  

(also called the cumulative frequency graph or cumulative frequency curve)

is a graph plotted from a cumulative frequency table. The following examples show

how to draw a cumulative frequency curve for grouped data
