Help on Analysis: Repeated measures? Split-Plot? Something else?I have a set of data that seemed straight forward, but now I am sure how to proceed. The experiment consisted of a single factor (fertilizer) with four treatments (fertilizer levels) and eight replicates (plants) of each treatment. Each replicate then had 5 data points collected on it (ie, 5 leaves from each plant were measured for area at a single time point).
I am not sure what the proper way to handle this data is. Do I consider this a repeated measures, since each replicate had multiple measurements? Can I consider the repeat observations as subplots and run a split-plot analysis? Or can I just average the data points for each replicate, and run an ANOVA?Re：幫助分析：重複措施？裂區？別的什麼？您可以使用自定義設計器並設置2因子分類設計。一個在4個水平（肥料量），另一個在8個水平9（植物類型）。我假設你使用了相同的肥料和不同量的肥料。生成32種處理組合後，您可以通過將列屬性修改為連續因子來重新編碼肥料水平，並相應地對其進行編碼並輸入低水平和高水平。可以將工廠測量的響應添加為單獨的列Y1至Y5，並且可以計算表示5次測量的平均值的第六列。此外，可以生成標準偏差的附加列響應。然後，您可以將平均增長和標準偏差建模回到連續施肥量和8種分類植物類型。希望這可以幫助。
