Sample Answer (Market Share of Companies)
This structured approach should help you and your group confidently prepare, create, and present a comprehensive report using pie charts to analyze real-world data.:
"Good morning, everyone. Today, I will present our analysis of the current smartphone market share. In our report, we focused on the market distribution among three major companies: Apple, Samsung, and Xiaomi, along with a category for other competitors.
As shown in this pie chart, Apple leads the market with a 27% share, followed by Samsung at 23%, and Xiaomi holds almost 14% of the market. The remaining 46% is divided among other smaller companies such as OPPO or VIVO. This distribution indicates that Apple’s strong brand loyalty has helped it secure the largest share, while Samsung benefits from diverse product range, and Xiaomi is gradually expanding its influence in niche segments.
Based on this analysis, we recommend that companies look into strategic partnerships and innovations to capture the untapped segments of the market. Thank you for your attention, and I look forward to discussing any questions you might have."
Now, let's include 'storytelling technique' in the presentation:
Do you see the difference?
Title: Telling the Story of the Smartphone Market
"Good morning, everyone. Imagine walking down the street—what do you see? People engrossed in their smartphones, scrolling through news, texting friends, or streaming videos. Now, have you ever wondered which company dominates this ever-growing market? Today, I will take you on a journey through the world of smartphone market share, exploring the strengths of key players and uncovering insights into their strategies.
Let’s begin with a story. Meet Alex, a university student who recently decided to upgrade his phone. He faced three main choices: an Apple device, a Samsung model, or a Google Pixel. Like Alex, millions of people make this decision every day, shaping the competitive landscape of the smartphone industry.
Now, let’s look at the data. Here’s a visual representation of the current market share. As illustrated in this pie chart, Apple leads with a 27% share, followed closely by Samsung at 23%, while Xiaomi holds almost 14%. The remaining 46% is shared among smaller competitors in which OPPO and VIVO can be found.
What does this tell us? Apple’s strong brand loyalty appeals to various consumer needs, from a tightly integrated ecosystem, and brand prestige. Samsung, on the other hand, thrives on broad product range, and from budget-friendly options to premium devices. Meanwhile, Xiaomi, though holding a smaller share, is steadily making inroads with its focus on software innovation and artificial intelligence features.
So, what’s next for the smartphone market? Our analysis suggests that companies aiming to expand their reach should consider strategic partnerships and invest in cutting-edge innovations, whether in battery life, AI, or seamless user experiences.
And that brings us back to Alex—his final choice? Well, that depends on which company tells the most compelling story through its products. Thank you for your attention. I look forward to discussing any questions you might have."
