Without careful planning, a study can easily fail to detect an existing effect by chance. This book teaches how to conduct power analysis for a range of models from correlation and t-test to structural equation models and multilevel models. Both a graphical Web software WebPower and an R package are introduced to practically conduct the analysis.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Ke-Hai Yuan, Zhiyong Zhang\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1946728020\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781946728029\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Isdsa Press\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 06\/09\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 358\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 2.53lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 11.00h x 8.50w x 0.93d","brand":"Ke-Hai Yuan","offers":[{"title":"Paperback","offer_id":43940300095743,"sku":"9781946728029","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/products\/img_ff23d71f-d3d5-42d3-9635-707a3993d203.jpg?v=1681446398","url":"https:\/\/www.whiterainbookhouse.com\/products\/practical-statistical-power-analysis-using-ke-hai-yuan-9781946728029","provider":"WR Book House","version":"1.0","type":"link"}
