Question

we will collect data about gender and height using our class. using the paper hanging in the laboratory, each lab group will measure their participant's initials and next to the initials record their reported gender.

results:150.22 female, 155 f, 154 f, 155.9 f, 156 f, 163.1 f, 154 f, 159 f 170.8 f, 167.6 f, 163.2 f, 168 f, 165 f, 166 f, 165 f, 160 f, 159 f, 163 f, 175 f, 175.3 f, 150 f

165.7 male, 175 m, 170.23 m, 174 m, 180m, 170m, 170.5 m, 179 m, 181 m, 180 m, 170 m, 169 m, 176 m, 180 m

1)using the data about height and gender that you will collect during lab and the information about scientific method, write a question about the sample/population you might ask and collect this data to investigate.

2)what hypothesis based on your question might you propose? remember hypotheses must be testable and falsifiable and can never be proven true. the evidence from your investigation can only provide support for the hypothesis.

3)what prediction might you make base on your question and hypothesis?

Answer 1

The data collected are:

Gender

Height

1) Using the collected data below research question can be framed

Does the mean height of male and females differ?

2) Hypothesis for the above question is framed as below:

Null hypohtesis: There is no significant difference in the mean height of males and females

Alternative hypothesis (Study hypothesis): There is a significant difference in the mean height of males and females

3) Based on the question and hypothesis, and also in general physically the difference in the height of males and females are expected. So, one can predict to reject the null hypothesis.
