One important attribute of a set of scores is its location, that is, where in the possible range between minus infinity and plus infinity the scores tend to fall. This can be described in a single number by usin
We seek a single measure (i.e. a statistic) that somehow represents the center of the entire data setS. The commonly used measures of central tendency are themean,median, andmode. Besides the normally studied mean (also called thearithmeticmean), we also consider two other types of mean: ...
Measures of central tendency locate a distribution of data along an appropriate scale. The following table lists the functions that calculate the measures of central tendency. The average is a simple and popular estimate of location. If the data sample comes from a normal distribution, then the s...
一、数据特征 众数(mode):在不分组数据中(ungrouped data)指数据中频率出现最高的数据;在分组数据(grouped data)中,频率最高的组为modal class; 平均数(mean)x¯=∑xb(ungrouped data)=∑fx∑f(grouped data) 中位数(median):对于奇数个数据,为第n+12个数据;对于偶数个数据,为xn2+xn2+12;对于成组数据...

Measures of central tendency do not provide information about the individual values of a data set. Rather, it is a set of numerical values that best represent or summarize the middle of the data set. The following measures can be used to determine the central tendency:...
Central tendency is a descriptive summary of a dataset through a single value that reflects the center of the data distribution.
In a normally distributed set of data, all three measures of central tendency are approximately the same. Using the data sample below, calculate the measures of central tendency. {1, 3, 8, 3, 7, 11, 8, 3, 9, 10}Mean (arithmetic)Since most populations exhibit normality (bell-shaped ...
