covariate

covariate的音标为[ˈkɒvɪəreɪt] ，基本翻译为“协变量”，速记技巧为“考为/ei/，娃/aɪ/”。

Covariate这个词的英文词源可以追溯到拉丁语，意为“共同变化的事物”。它的变化形式包括复数covariates和过去式covariated。

相关单词：

covariation：共同变化，一致性

covariate analysis：协变量分析，相关分析

covariate adjustment：协变量调整，校正

例如，在医学研究中，协变量分析是一种统计方法，用于评估两个或多个变量之间的相关性，同时考虑其他可能影响结果的变量。协变量调整则是在统计模型中考虑到可能影响结果的其他因素，以提高模型的准确性和可靠性。这些词汇都与covariate密切相关，反映了科学研究中对变量之间关系的关注和探究。

常用短语：

1. covariate factor

2. covariate effect

3. covariate adjustment

4. covariate selection

5. covariate balance

6. covariate monitoring

7. covariate independent

双语例句：

1. The covariate balance between the two groups was excellent. (两组的协变量平衡度非常好。)

2. Covariate adjustment was made for age and gender. (对年龄和性别进行了协变量调整。)

3. Covariate monitoring is crucial for ensuring the accuracy of data analysis. (协变量监测对于确保数据分析的准确性至关重要。)

4. The covariate effect of exercise on mental health should not be ignored. (运动对心理健康的协变量效应不容忽视。)

5. Covariate adjustment should be done carefully to avoid introducing bias into the analysis. (进行协变量调整时应小心谨慎，以避免引入偏误。)

英文小作文：

When conducting research, it is crucial to consider covariates, which are factors that may affect the results of a study. For example, age, gender, and diet are common covariates in medical research. By carefully balancing these factors between groups and making appropriate adjustments during analysis, researchers can ensure that their findings are reliable and accurate. However, covariates can also be complex and challenging to manage, especially when dealing with large datasets. Therefore, it is essential to have a clear understanding of the research question and the potential impact of covariates on the results. By doing so, researchers can make informed decisions about how to approach their analysis and ensure that their findings are reliable and accurate.
