For example, it would be interesting to find out, the average passes made by a footballer in a match. The values about all the, variables defined in this paper are all based in empirical data. Such designs are more efficient than other experiments as they provide more, information at a similar or even lower cost. 1 0 obj
So overall, either edge, weight shows the total numbers of calls or total duration of calls is G weighted during statistical, According to Gjermeni (2016), results of this study after simplification, the network graph, connect to a single vertex and no pair of vertices with more than one edge between them. Analysis is a verb, it is a dynamic, thoughtful process that turns raw data into something meaningful and insightful. The full Variable Labels (rather than abbreviated Variable Names) are displayed by default here. Describing statistics. summarizes the entire set of data/measurements which are a central to the complete set. การประเมินผลการฝึกทักษะด้วยแบบประเมินการฟื้นสภาพผู้ป่วยบาดเจ็บที่สมองของ Rapport et al (1982) ซึ่งได้ผ่านการตรวจสอบความตรงตามเนื้อหาจากผู้ทรงคุณวุฒิจำนวน 5 ท่าน และหาค่าความเที่ยงของการสังเกต (Interrater reliability) เท่ากับ 0.83 และ 0.85 ตามลำดับ และประเมินการรับรู้ภาระผู้ดูแลของผู้ดูแลด้วยแบบประเมินที่ดัดแปลงมาจาก Oberst (1990) ซึ่งได้ผ่านการตรวจสอบความตรงตามเนื้อหาจากผู้ทรงคุณวุฒิและหาค่าความเที่ยงสัมประสิทธิ์อัลฟาครอนบาคเท่ากับ .92 สถิติที่ใช้ในการวิเคราะห์ข้อมูล ได้แก่ ค่าเฉลี่ย ส่วนเบี่ยงเบนมาตรฐานและการทดลองที ผลการวิจัยสรุปได้ดังนี้ การรับรู้ภาระการดูแลของผู้ดูแลภายหลังได้รับโปรแกรมฯของกลุ่มทดลองมีค่าต่ำกว่ากลุ่มควบคุมอย่างมีนัยสำคัญทางสถิติที่ระดับ .05 และการรับรู้ภาระผู้ดูแลของผู้ดูแลกลุ่มที่ได้รับโปรแกรมฯต่ำกว่ากลุ่มที่ได้รับการพยาบาลตามปกติอย่างมีนัยสำคัญทางสถิติที่ระดับ .05 การฟื้นสภาพของผู้บาดเจ็บที่สมองภายหลังได้รับโปรแกรมฯดีกว่าก่อนได้รับโปรแกรมฯอย่างมีนัยสำคัญทางสถิติที่ระดับ .05 และการฟื้นสภาพของผู้ป่วยบาดเจ็บที่สมองในกลุ่มที่ได้รับโปรแกรมฯดีกว่ากลุ่มที่ได้รับการพยาบาลตามปกติอย่างมีนัยสำคัญทางสถิติที่ระดับ .05 This quasi experimental research aimed to investigate the effects of supporting knowledge of family caregiver program on caregiver burden, and recovery of brain injury patients.
