Q: Why do we need to interpret data
because different way of saying data can leads to emotional difference (we associate 20 as low number where as 90 as high number)
because different reader probably care about different aspects of data
Q: What is the importance of presenting data accurately
Data: not just numerical, include words, observations, experiences
Second question: use of the word "small"
Presenting data for different people
Subtitles of data charts should tell story:
"Table 2.2below illustrates the difference between describing data and telling a story about data." instead "Figure 2.1 shows Twitter use and relationship length"
hope readers will misinterpret data
believe small differences are large (or vice-versa)
leaving off important context
exaggerating the conclusion
Correlation != Causation
story: interpretation of significance of data describing data: numbers from the graph hedging: using words like "appear to"
