Text Component | Literal Content | Simple Interpretation |
---|---|---|
Graph Type | time graph | The data shows how values change over time |
Metric | percentage market share | The metric is how much of the market each platform controls (in percent) |
Compared Entities | each of the platforms | Several different platforms are being compared |
Time Unit | each financial quarter | Time is split into 3-month intervals (quarters) |
Date Range | between 2007 and 2011 | The data covers a period from 2007 to 2011 |
Table 2: Chart Analysis
Chart Component | What is Shown | Analysis |
---|---|---|
Lines | Each platform's market share as a separate line | Shows the trajectory of each platform's popularity over time |
X-Axis | Financial quarters from 2007 to 2011 | Visualizes how things change every quarter |
Y-Axis | Percentage market share (\(0\%-70\%\)) | Lets us see which platforms are dominant/increasing/decreasing |
Trend Highlights | Symbian declines, Android rises, others mostly stable/decline | Indicates a significant market shift from Symbian to Android during the period |
Intersection Point | Android's line crosses Symbian's | Marks the specific quarter when Android overtook Symbian in market share |
Key Insights
- Android's market share started at \(0\%\) in 2007 and grew rapidly, overtaking all other platforms by 2011.
- Symbian began with the highest market share in 2007, but steadily declined and was surpassed by Android around late 2010 or early 2011.
- At the point where Android first surpassed Symbian (the lines cross), iOS's market share was relatively stable and much lower than either, indicating Android became the dominant platform.
Step-by-Step Solution
Question 1: Time from \(1\%\) Market Share to Surpassing Symbian
Complete Statement:
From the time the Android operating system achieved \(1\%\) market share, it took [BLANK] months more to surpass Symbian in worldwide percentage market share.
Breaking Down the Statement
- Statement Breakdown 1:
- Key Phrase: Android operating system achieved \(1\%\) market share
- Meaning: Identify when Android first reached \(1\%\) of worldwide smartphone market share.
- Relation to Chart: Look for the first data point or quarter where Android's line rises above the \(1\%\) horizontal mark.
- Important Implications: This is the starting point for our time interval.
- Statement Breakdown 2:
- Key Phrase: surpass Symbian in worldwide percentage market share
- Meaning: Determine when Android's market share becomes greater than Symbian's.
- Relation to Chart: Find where the Android line crosses and overtakes the Symbian line.
- Important Implications: This is the ending point for our time measurement.
- What is needed: The number of months between Android reaching \(1\%\) market share and the point where it surpasses Symbian.
Solution:
- Condensed Solution Implementation:
Locate when Android first exceeds \(1\%\), then determine the subsequent quarter when Android overtakes Symbian, and count the months in between. - Necessary Data points:
Android achieves \(1\%\) market share around Q1 2009; it surpasses Symbian by Q4 2010. - Calculations Estimations:
Q1 2009 to Q4 2010 is 7 quarters. \(7 \text{ quarters} \times 3 \text{ months} = 21 \text{ months}\). However, Android may have reached \(1\%\) slightly earlier—end of 2008—bringing the total closer to 26 months, matching the closest provided option. - Comparison to Answer Choices:
Given the options (8, 26, or 30 months), 26 months is the best fit.
FINAL ANSWER Blank 1: 26 months
Question 2: Android vs iOS Market Share Ratio
Complete Statement:
In the quarter before Android surpassed Symbian in worldwide percentage market share, Android was [BLANK] the size of Apple's iOS system.
Breaking Down the Statement
- Statement Breakdown 1:
- Key Phrase: In the quarter before Android surpassed Symbian
- Meaning: Focus on the data for the quarter directly before Android overtakes Symbian.
- Relation to Chart: Select the market share values from that specific quarter.
- Statement Breakdown 2:
- Key Phrase: Android was [BLANK] the size of Apple's iOS system
- Meaning: Compare the market shares of Android and iOS as a ratio.
- Relation to Chart: Divide Android's percentage by iOS's percentage to determine if it is less than, equal to, or more than twice as large.
- What is needed: Whether Android's market share was less than, equal to, or more than twice iOS's share in the relevant quarter.
Solution:
- Condensed Solution Implementation:
Check the market share percentages for Android and iOS in Q3 2010 (the quarter before Android overtook Symbian), and calculate the ratio. - Necessary Data points:
Android: approximately \(32\%\), iOS: approximately \(15\%\) in Q3 2010. - Calculations Estimations:
Ratio = \(32 ÷ 15 ≈ 2.13\). This is more than twice. - Comparison to Answer Choices:
Answer choices are 'More than twice', 'Twice', or 'Less than twice'. The correct answer is 'More than twice'.
FINAL ANSWER Blank 2: More than twice
Summary
To answer both questions, we identified the quarters where Android first reached \(1\%\) market share and later surpassed Symbian, calculated the time between these events, and compared Android's market share to iOS's at the relevant point. The answers are: 26 months for question 1, and 'More than twice' for question 2.
Question Independence Analysis
These two questions are independent: question 1 is a time-based calculation, while question 2 is a comparison of market share ratios at a specific point. Solving one does not rely on information from the other.
