# THE SAMPLING PROCESS

by idzyan ismail
# 1. 1. Define The Population

## 1.1. Meaning

### 1.1.1. The target population must be defined in terms of elements, geographical boundaries, & time

## 1.2. Example

### 1.2.1. Expatriate in Klang Valley Hotel

### 1.2.2. Reading habits of elderly - target population is ppl aged 50 and over

## 1.3. Important

### 1.3.1. Illustrate that the research objective & the scope of the study

# 2. 2. Determine The Sample Frame

## 2.1. Meaning

### 2.1.1. Is a (physical) representation of all elements in the population from which sample is drawn

# 3. 3. Determine The Sampling Design

## 3.1. Types Sampling Design

### 3.1.1. Probability

3.1.1.1. Element in the population have some known,non-zero chance or probability of being selected as sample subjects.

3.1.1.2. Use when Representativeness of the sample is of importance in the interests of wider generalizability.

### 3.1.2. Non-Probability

3.1.2.1. Element do not have known or predetermined chance of being selected as subjects

3.1.2.2. Used when time or other factors, rather than generalizability become critical.

# 4. 4. Determine The Sample Size

## 4.1. Factors affecting sample size

### 4.1.1. The research objective

### 4.1.2. The extent of precision desired

### 4.1.3. The acceptable risk in predicting that lvl of precision

### 4.1.4. The amount of variability in the population itself

### 4.1.5. The cost & time constraints

### 4.1.6. The size of population

# 5. 5. Executing The Sampling Process
