如上图所示,红色的箭头对应的横坐标为1%,纵坐标为20%的点。这里横坐标上每个数字都代表了它两头一个区间的中点。该中点对应的纵坐标可以用来确定该区间内数据发生的个数。比如1%是区间0-2的中点,1%对应的纵坐标就是20,所以发生在0-2这个区间内的数据个数就是20.
以此类推,在本题中像横坐标1%这样正数对应的纵坐标就代表发生货币升值时的期数,反之例如-1%这样负数对应的纵坐标就代表贬值的时发生时期数。这题中,大部分期数(26/48)都位于升值状态。所以本题选A

弱弱地问下2%-4%这个区间有6个取值是怎么看出来的呢。。。。。。。

这道题26是怎么看出来的呀,纵轴每个点对应几有点看不明白
