# statistical test for pregnancy data

Not what you're looking for?

The hypothesis is that the more hours a female spends in school the less likley she is to become pregant.

1.Conduct a descriptive data analysis that includes the following: a) a measure of central tendency; b) a measure of dispersion and c) at least one graph.

2.Briefly interpret the descriptive data analysis.

3.Conduct the appropriate statistical test that will answer your hypothesis. (regression analysis, single t-test, independent t-test, cross-tabulations, Chi-square, or One-Way ANOVA.) Explain your justification for using the test based on the type of data and the level of measurement that the data lends to for the statistical analysis.

4. Report and interpret your findings. Use APA style and include a statement about whether you reject or fail to reject the null hypothesis.

Answers

1. Conduct a descriptive data analysis that includes the following:

a) A measure of central tendency;

Mean = = 4.69

Median = item when the items are arranged in ascending or descending order of magnitude.

= 4.75

b) A measure of dispersion and

Range = Highest observed value - Lowest observed value

= 8 - 0

= 8

Sample variance = = 6.080510204

Sample standard deviation = = 2.465869057

2. Briefly interpret the descriptive data analysis.

Mean is defined as the arithmetic average of data, that is, the sum of all the numbers divided by the number of observations contributing to that sum. The mean represents the balance point, or centre of gravity of the distribution and it is the most common measure of central tendency. Thus the hours spent by females in school is centred about 4.69 hours.

Median is the middle most observation of the data, determined after all items are arranged in ascending or descending order of magnitude. In other words, median is that observation above which and ...
