This article will be sharing with you about the ideas and lecture notes regarding the data analysis for environmental and public health studies. The lecture content will be focussing on the data management, hypothesis testing, and the variable identification. The list of the lecture content can be found below. Please click on the respective article to learn more about the discussion of the content, quizzes and also applicable notes and exercises.

  1. Introduction to data analysis in environmental health research methodology (Part I)
  2. Descriptive and analytical epidemiological statistic (Part II)
  3. Normality assessment and tabulation of data for determining appropriate statistical test (Part III)
  4. Analysis of data using hypothesis testing for environmental health research (Part IV)
  5. Demonstration of data analysis using SPSS for Chi-Square Application in Epidemiological Study (Part V)

The data analysis chapter for above mention topics can be summarized as follows:

Mengenalpasti maklumat-maklumat dalam proses penganalisaan data seperti:

  1. Maklumat sampel (profile) termasuk elemen demographic;
  2. Menganalisis faktor yang terlibat dalam kajian;
  3. Pengesahan dan kepersisan (reliability dan validity;
  4. Membuat ujian hipotesis berdasarkan elemen epidemiologi penyakit;

Menerangkan maksud dan kegunaan ujian statistik:

  1. Menerangkan data-data yang bakal diperolehi dari kajian penyelidikan;
  2. Maklumat kajian yang dieprolehi dan analisa serakan;
  3. Pembinaan ujian hipotesis dan kaedah menjawabnya berdasarkan statistik;
  4. Analisa data peringkat pertengahan dalam menjawab persoalan hipothesis;
  5. Persembahan data dan maklumat;
  6. Penerangan informasi mengenai bahagian keputusan dan analisa data.

Menghuraikan jenis-jenis analisa
