纵向比较用英语怎么说

"Longitudinal comparison" is a term that is used to describe the process of comparing something over a period of time or along a specific dimension. This term is often used in research and data analysis to refer to the process of collecting and analyzing data from a single group or individual over a period of time, in order to understand how certain variables or factors change or remain stable over time.
Here are some examples of how "longitudinal comparison" can be used in a sentence:
"The researchers conducted a longitudinal comparison of the impact of different educational programs on student achievement." (研究人员对不同的教育计划对学生成绩的影响进行了纵向比较。)
"The study used a longitudinal comparison design to examine the relationship between diet and heart disease." (该研究采用了纵向比较设计来研究饮食与心脏病之间的关系。)
"The data from the longitudinal comparison showed that the intervention had a significant effect on the outcome measure." (纵向比较的数据表明，干预对结果测量有显著的影响。)
The term "longitudinal comparison" is derived from the Latin word "longitudo," which means "length" or "long duration," and the prefix "longi-" is often used in English to describe things that are related to length or duration. In this case, the term "longitudinal" refers to the process of comparing something over a long period of time or along a specific dimension.
