View answer resolution

【Answer to question 1】A

【analysis】

A is correct. Any descriptive measure of a population characteristic is called a parameter.

B is incorrect. A sample statistic is a quantity computed from or used to describe a sample.

C is incorrect. A frequency distribution is a tabular display of data summarized into a relatively small number of intervals.

【Answer to question 2】B

【analysis】

B is correct. A candlestick chart includes four prices per data point entry: the opening and closing prices and the high and low prices during the period. If constructed with daily data points, the daily intraday price performance will be evident in this type of chart.

A is incorrect. Line charts only show one price per data point, typically the closing price, which will not demonstrate intraday price performance.

C is incorrect. Point and figure charts record the number of price changes over time, but not based on a consistent time scale. Consequently, definitive intraday information is not necessarily available

成功=时间+方法，自制力是这个等式的保障。世上无天才，高手都是来自刻苦的练习。而人们经常只看到“牛人”闪耀的成绩，其成绩背后无比寂寞的勤奋。小编相信，每天都在勤奋练习，即使是一点点的进步，大家一定可以成为人人称赞的“牛人”。更多CFA考试资讯，点击了解>
