标题: 拉丁方设计是否解决了顺序效应问题？
如题。组内设计最难避开顺序效应问题。拉丁方能解决吗？

顺序变量和自变量之间不存在交互作用

这个前提我总是想不明白是什么意思

昨天看到一本书上，讲拉丁方设计能避开顺序效应，但会有carryover effect （听过两个译法，延续效应遗留效应）

以下是carryover effect 的解释
A carryover effect is an effect that "carries over" from one experimental
condition to another. Whenever subjects perform in more than one condition (as
they do in within-subject designs) there is a possibility of carryover effects.
For example, consider an experiment on the effect of rate of presentation on
memory. Subjects are presented with a list of words and asked to recall as many
words as they can. In one condition, the words are presented one word per
second; in the other condition, the words are presented two words per second.
The question is whether or not having performed in one condition affects
performance in the second condition. Perhaps learning the first list of words
will interfere with learning the second list because it will be hard to remember
which words were in each list. Or maybe the practice involved learning one list
will make it easier to learn a second list. In either case, there would be a
carryover effect: performance on the second list would be affected by the
experience of being given the first list.

它就是为了解决组内实验的被试顺序问题的。

如果不能控制顺序效应，那还叫拉丁方设计吗

延续效应应该是可以平衡的

不能平衡的是差异延续效应。

可以参考坎特威兹的实心
