Trimean is a measure of central tendency, like mean, median and mode. Its meaning is sometimes confusing because it is defined in a manner different from these traditional measures of central tendencies. Mathematical Formulation The trimean is defined as the weighted average of themedianand the ...

Which of the following is a measure of central tendency? A. Range B. Variance C. Mean D. Standard deviation 相关知识点: 试题来源: 解析 C。平均数(mean)是一种集中趋势的度量。极差(range)是描述数据分散程度的。方差(variance)和标准差(standard deviation)也是描述数据分散程度的。
The mean is a measure of central tendency, which is a type of descriptive statistic value. The mean can be simply defined as the average value of a set of data. The standard deviation is a measure of spread, which is a type of descriptive sta...
A measure of central tendency is a single value that attempts to describe a set of data by identifying the central position within that set of data. As such, measures of central tendency are sometimes called measures of central location. They are also classed as summary statistics. The mean ...
To determine the median value in a data set, the numbers must first be sorted or arranged in order of magnitude. As a result, the median is less affected by outliers and skewed data. This property makes it a better option than the mean as a measure of central tendency. ...
The number of values is the total frequency. This can be abbreviated to n.n.n. You can use an extra column to help. Mean is a measure of central tendency. It is a value that can be used to represent a set of data. For example, The frequency table shows the number...
Central tendency: The mean is used as a measure of central tendency in a data set. Group comparison: Means are compared between different groups to identify differences in psychological variables. Quantifying behavior: The mean is used to quantify behavior in psychological research studies. ...
Which of the following is not a measure of central tendency? A. Mean. B. Median. C. Mode. D. Standard deviation. 相关知识点: 试题来源: 解析 D。平均数(mean)、中位数(median)和众数(mode)都是衡量数据集中趋势的指标,而标准差(standard deviation)是衡量数据离散程度的指标。
