Introduction In this essay I will be critiquing two research studies which examine the impact infant massage classes have upon the health and wellbeing of mothers and their infants. This topic was chosen in order to begin to assess the evidence base for its current inclusion in Health Visiting Services. Infant massage has been used as a health promotion tool for several years. I am currently teaching it as part of a Postnatal Support Programme and in my experience parents appear to enjoy and value

It becomes more efficient to test the same set‚ because the audit team could request a comprehensive documents package from the client. The sample size table in Appendix A indicates that a sample size of 58 is acceptable for the first control‚ but the higher estimated population deviation rate for the second control suggests that a larger sample size of 77 is necessary

distribution when the null hypothesis is true‚ or any in which this is asymptotically true‚ meaning that the sampling distribution (if the null hypothesis is true) can be made to approximate a chi-square distribution as closely as desired by making the sample size large enough. The Chi-Square ( ) test is the most popular non-parametric test/methods‚ to test the hypothesis. The symbol is the Greek letter “chi”. Like other hypothesis testing procedures‚ the calculated value of -test statistics is compared
