I believe that men have a larger range, larger inter-quartile range and standard deviation of IQ and Average Key Stage 2 Result than women but have a similar median, this means that men are, at times, smarter than women and, at times, dumber than women.

Introduction

Matthew Edwards                10D2

Statistics

Hypothesis:

        I believe that men have a larger range, larger inter-quartile range and standard deviation of IQ and Average Key Stage 2 Result than women but have a similar median, this means that men are, at times, smarter than women and, at times, dumber than women.

Test The Hypothesis:

        I believe this because looking at the statistics I see clever men and dumb men but women seem to stay around the average mark. I am using a set of secondary data provided by my teacher of pupils from Mayfield School. My hypothesis uses three of the columns; Gender, IQ and Average Test Score, which I worked out my self.

                My sample size is 100 out of 1183 because 1183 is too large for me to Analyse. I am going to use a stratified sample of men and women. There are 579 women and 604 men out of the 1183 people. I am using a stratified sample to keep the samples in proportion of the population this should help eliminate bias.

604 / 1183 * 100 = 51.06 ≈ 51

579 / 1183 * 100 = 48.94 ≈ 49

        I have 51 men and 49 women to sample, I will use my calculators Random number button the multiply it by 1183 I will repeat until all the samples have been taken. If I get a number twice I will redo it. Press the shift button the press Rnd with Rnd#

    It is Medea's subordinate and disempowered status in this society, not only as a woman but also as foreign women that leads her to proclaim "we women are the most unfortunate."
