The term statistics of health is the summarized data that is related to the health of the patient in the particular healthcare center. The researchers collect the data from the healthcare organization and use this data for the learning about the health of the public and about the health care of the patients. The analysis of the data in public healthcare helps in understanding the factors that are associated with the outcomes of the desired interest (Bachner, 2021). It is also used for determining the extent to which the different kinds of interventions may be effective. This model will help in the development of the knowledge of the statistic, designing of the statistical data appropriate execution and plan for addressing the question related to the health of the public. The methods that have been used for analyzing the statistics data of the public health are mean, median T test and standard deviation and many more for the data analyzing. There should be employment of the formats of the graphs like pie chart, histogram and line graphs for presenting the data epidemiologically (Ott, 2018). In the report the data obtained was a randomized trial of control that is conducting for evaluating the education intervention of lifestyle health. The proposed intervention is delivered for the 12 weeks and the main aim of this intervention would be the promotion of the healthy lifestyle amongst the students of the university and also increasing the literacy related to the health and improving healthy weights in participants of study.
The analysis of the preliminary that is discussed on the screening of the data and the statistics of the description like the mean, standard deviation, frequencies like percentages and counts and medians, charts and graphs would also be used in summarizing the variables of these assessments of public health care.
Question 1
Here the difference between the healthy literacy of the two campuses of compus A and Campus B has been reflected through the “independent T test” in the SPSS.

Equal variances not assumed .065 17.637 .949 .26629 4.10265 8.36580 8.89838
The difference has been concluded on the basis of the Asthma variable and comparing the two variables together, that is baseline health literacy and the literacy of the health after the intervention (Peng, 2018). In the baseline health literacy the no of the people using the smoking are the No asthma of 69 and having 12 similarly in literacy of health after the intervention is the same. The P value of both the campuses are 0.246 and 0.267 respectively. The Tstatistics and the P value of the test has been reflected in the valve table (Baek et al. 2018). The test is performed using the “nonparametric equivalent” technique for comparing the dependent variable on the two interventions in the “MannWhitney test”. Here the grouping variables are Asthma. “MannWhitney test indicates that there is not any difference of significant in the test between the literacy and health of the two campuses. (U= 407 and 408 respectively)

As per the “Body mass index” the evaluation of the effect on the intervention of the “body mass index” has been conducting by using the statistical T test of the independent variable in the SPSS software, at first there should be the understanding of the T test, this is basically used for the finding out the difference between the two groups mean and how they are related with each other. This is used for the test of the hypothesis and the values of the T test and determining the significant statistic (Bahariniya and Madadizadeh, 2021). From the above table it can be clearly seen that the what the values of the means of the two groups are in the Body mass index one the sample size in the control group is 47 and in intervention group it is 34 the mean value are 227512 and 254355 respectively and standard deviation is 32330 and 46664 respectively (Rahman, 2020). P values of the T test are 0.003 and 0.006 and the T values are 3.060 and 2.890 respectively and there is 95% of the difference of confidence.

The use of the cross tabulation has been done for conducting the answer of this question. By the use of this table the significant statistical difference of the cases of the Asthma and the intervention group and the control group (Benke and Benke, 2018). There has been a total 81 no of the people in which the control group has the 40 cases without Asthma bad with Asthma it is 7 persons and the total percentage is 58% for the group of the control (Wing et al. 2018). In the intervention group the no of the no Asthma cases are 29 and with Asthma are 5 and there total no of participants in the control group are 47 nad in intervention group are 34 in whole total it was 69 no of people without having the Asthma and 12 propels are with Asthma.
“Chi square test”
If the value of the calculated “Chi square” is higher than the critical value of the chi square there was the chance of rejecting the hypothesis of null (Berman, 2018). This signifies that the how much of the differences are there between the counts observation and the the no of the counts that has been expected, the value of the “Chi square” that is calculated is 0.001 and the value of p is 0.981, the results can be said to be significant as the value is less and equal to the designated level of the alpha that is normally is 0.05 (Wong et al. 2019). Here the “P value” is greater than the “standard value” of alpha so we reject the “hypothesis of null”.

Question 4
In question 4 the determination should be made on the difference between the baseline health literacy between the participants of the age groups of the “≤20 years, 2125 years and ≥26 years”. For this the test has used the cross tabulation for making out the difference according to the age criteria. There is the total number of the participants of the 8 (Chen, 2022). As per the calculation has been made on the basis of the health literacy baseline it can clearly show what none of the people have come on the criteria of the range. In the below table it can be seen that the no of participants in the age group of the less than 20 are 29 which is the highest no of participants in the three age group criteria (Zhao et al. 2021). In the age group of the between 21 to 25 years the no of participants are 19 and in the last age group of the age of more than 26 are 27. Tha total no of the participants in all the age groups are 72.

Question 5
For the conduction of the analyzation and investigation of the baseline literacy of health, sex and age for predicting the body mass index of the post intervention amongst the participants. For this investigation the test of the “Univariate Analysis of Variance” Has been in the use for the calculation (EscolàGascón, 2022). This tells us the analysis of the Univariate of each variable of the set of the data. It will look at the value range and the values central tendency, it describes the response pattern of the variables, and it describes each variable in its own way.
“Health literacy at baseline and postintervention body mass index”
The highest no of the participants in the literacy of health in the criteria of 57.14 that is 12 participants.
“Age and postintervention body mass index”
The age range of the starting from the 18 years to the 44 years the no of the highest participants in the age range of the 20 age, this has the participants of 14 people in it 19 years is the second highest age range.
“Sex and postintervention body mass index”
As per the criteria of the sex the no of the participants in the male is 26 and in female is 55, the female participants are highest.
The descriptive statistics of the having the dependent variable of Body mass index of 2 with the factors of “Health literacy at baseline”, age and sex has been determined (Hernán et al. 2018). The highest mean values of the male and female are 376917 and 376917 respectively for male and female. This comes in the baseline of the health literacy of 41. The total value of the mean of male is 250504 and for female it is 229550 in total it is 236276.

Conclusion
The conclusion of this report summary is that the different tasks have been done on the basis of the different tests and different formulas of the tasks. In the tasks 1 the conclusion is made by applying the T test of the and comparison is made on the basis of the mean of the variables for examining the difference between the baseline of the health literacy between the different campus of campus And campus B. in the second task the evaluation is done on the intervention and the BMI of the participants, the body mass index has calculate by using the formula and then the evaluation has done on the intervention groups and control groups. In the third the examination of the significant statically of the no of the Asthma cases between the control and intervention groups has been done. This reflects the number of participants in every the groups having Asthma or not. In the fourth task the determination of the significant difference of the statistics of the baseline of the health literacy between the participants of the age criteria of the “≤20 years, 2125 years and ≥26 years' '. For this the test has used the cross tabulation for making out the difference according to the age criteria. At last for the task 5 the investigation of the how the baseline literacy of healthy, sex and age can be used for the prediction of the body mass index of the post intervention between the participants.
