State the purpose of the questionnaire, who will be questioned, and how they will be questioned. You decide the purpose, the type of questions used, and whether the questionnaire is administered in person or through email. You must also decide on the most appropriate sampling technique to use. This considers who should receive the questionnaire (e.g., a random sampling, sampling from specific groups of people with similar characteristics, sampling from different locations, sampling from people who have used a product you are asking about, a sampling from a convenient group, etc.).

Answer 1

1. Topic of the Questionnaire:

The questionnaire will focus on consumer preferences and satisfaction regarding electric vehicles (EVs). This topic is relevant as the market for electric vehicles is rapidly expanding, and understanding consumer perceptions can guide manufacturers in product development and marketing strategies.

2. Target Group for Data Collection:

I will target current electric vehicle owners and individuals considering buying an electric vehicle. The reason for this specific targeting is to gather insights from individuals who have firsthand experience with electric vehicles, as well as those who are contemplating their purchase. This dual perspective can provide comprehensive insights into the factors influencing decisions in the EV market.

3. Where the Survey Will Be Conducted and Sampling Technique:

The survey will be conducted primarily through email invitations to individuals who have recently registered electric vehicles or shown interest in purchasing them. To select respondents, I will use stratified sampling, which involves dividing the respondents into subgroups based on their characteristics (e.g., current EV owners, potential buyers) and then sampling from each group. This approach helps ensure representation from both segments and can lead to more nuanced insights.

4. Type of Questions Used:

I will use a combination of both open and closed questions. Closed questions will allow for quantitative analysis, whereas open questions will provide rich qualitative insights.

5. Advantage and Disadvantage of Open Questions:

• Advantage: Open questions allow respondents to express their thoughts freely and provide in-depth insights, which can uncover nuances and unexpected themes related to their experiences.
• Disadvantage: Analyzing open-ended responses can be time-consuming and subjective, making it challenging to quantify results and draw definitive conclusions.

6. Advantage and Disadvantage of Closed Questions:

• Advantage: Closed questions simplify the analysis process since responses are limited to predefined options, making data quantifiable and easy to compare across respondents.
• Disadvantage: They may restrict the depth of responses and fail to capture the complexities of respondents' thoughts or feelings about electric vehicles.

7. Example of a Question:

• Question: "What are the top three factors influencing your decision to purchase an electric vehicle? (e.g., cost, environmental impact, brand preference, technology, etc.)" This question combines a closed structure (top three factors) with an open element (the factors themselves).

8. Type of Graph to Summarize the Data:

I would choose a bar graph to summarize the data for the aforementioned question. A bar graph effectively displays the frequency of responses for each factor influencing EV purchase decisions, allowing for easy comparison of the relative importance of each factor among different respondents.
