Misleading Graphs

    Elapsed scenario time of two charts are same, but the scale Average Response of time  are different. Left chart each scale is 10 seconds, but the right chart is 0.1 second of interval. So the right chart's speed is faster than the left one.

    When we read the chart, we should be careful for the scale. Note that the chart value and the statistical table conversion work of the difference between the two numbers.

communication mode

In the class, we learn how to call person of different relations. I like to use Wechat and message for my friends, family or someone else. If i sent for my family, my best friends, i can use casual calling for them. When i talking with them, it can improve my expression, writing and have enough time to express my idea for them. When i can't express clearly, i can use message, writing maybe will better to understand for them. If i have some important things that should have a evident, i can type or write down. Two persons know each other not a long time, of course they can use different kinds of communication channels.
