Data Volleyball Study

Data colums 1-14 contain demographic information related to participants (e.g., gender, age, handedness, volleyball league played etc.). Then, their scores on the MRF 3 are reported prior to receiving the PPR (PreWorried, PreTense, PreNotConfident) and after receiving the PPR (PostWorried, PostTense, PostNotConfident). Thereupon, accuracy scores for the serves prior to PPR are provided (PreShot1-10). The lower the score, the less the distance to the target. These scores are followed by the numbers of errors made prior to PPR use (PreOuts, PreNetzs, Pre_Errors). Accuracy scores for the serves after the routine are provided (PostShot1-10) and agin errors after PPR use (PostOuts, PostNets, Post_Errors). After this, the average accuracy prior to PPR (PreShotsDis) and after PPR (PostShotsDis) as well as SDs for both are provided (PreShotsSD, PostShotsSD). Last summarized anxiety scores for the MRF 3 (anxiety_pre, anxiety_post) and number of errors per player (Errors) are presented.

本数据集的第1至14列为与受试者相关的人口统计学信息（例如性别、年龄、利手性、参与的排球联赛组别等）。随后，报告了受试者在接受PPR干预前的MRF 3量表得分（包含PreWorried、PreTense、PreNotConfident三个维度），以及接受PPR干预后的MRF 3量表得分（包含PostWorried、PostTense、PostNotConfident三个维度）。紧接着，给出了受试者在接受PPR干预前的发球准确率得分（PreShot1至PreShot10），该得分越低，代表发球距离目标的偏差越小。在上述发球准确率得分之后，列出了受试者在使用PPR干预前出现的各类失误次数（PreOuts、PreNetzs、Pre_Errors）。随后给出了该流程结束后的发球准确率得分（PostShot1至PostShot10），以及受试者在使用PPR干预后出现的失误次数（PostOuts、PostNets、Post_Errors）。在此之后，给出了受试者在接受PPR干预前的发球平均准确率（PreShotsDis）、干预后的发球平均准确率（PostShotsDis），以及两组准确率的标准差（PreShotsSD、PostShotsSD）。最后，列出了经汇总的MRF 3量表焦虑得分（anxiety_pre、anxiety_post）以及每位受试者的总失误次数（Errors）。
