| Theme: | | | | minimum value for men is 98. |
| The theme of this study is to determine whether | | | | Outliers: |
| men are smarter than women or whether | | | | This section determines whether there are |
| women are smarter than men, in the past men | | | | outliers in the data set, combining all the data |
| have been considered to play major and most | | | | values the minimum and maximum values are as |
| important roles in the society. For example men in | | | | follow |
| the past have held high position in the society in | | | | Minimum=98 LQ-1.5QR , UQ+1.5QR IQR=UQ-LQ |
| leadership, and there are more men than women | | | | Lower Quartile=106 106-1.5(13), 119+1.5(13) |
| who are leaders of the important institutions in | | | | IQR=119-106 |
| the society. The society in the past perceived | | | | Median=108 106-19.5 , 119+19.6 IQR=13 |
| women to be weak and less intelligent and their | | | | Upper quartile= 112 (86.5 , 138.5) |
| only position in the society included taking care of | | | | Maximum=119 |
| children. This perception has however changed and | | | | Therefore the data set should range from 86.5 to |
| women today are holding top positions, the | | | | 138.5, given that the minimum value of the data |
| following study analysis data for an IQ test from | | | | set and the maximum value of the data set are |
| a sample of 5 mean and 5 women. | | | | within this range then outliers do not exist in the |
| Reason for choosing this case: | | | | data set. |
| I choose to study this particular concept because | | | | Hypothesis test: |
| of the fact that women in past have been less | | | | A T test is appropriate for this study given that |
| powerful and through this analysis this would | | | | there are only two categories to consider, the |
| enable me to understand why women do not hold | | | | following is the hypothesis tested: |
| top positions in the society, also to analyze why | | | | Null hypothesis; |
| women do not hold position whether this is | | | | Ho: q1 =q2 |
| because they are less intelligent or whether this is | | | | Alternative hypothesis: |
| because men discriminate against them. | | | | H1:q1> q2 |
| Sample: | | | | Where Q1 is the male IQ test score mean and |
| The population in this study is male and female in | | | | Q2 is women IQ test score mean, using excel |
| the university, a stratified sample was obtained | | | | data analysis tool the following results were |
| comprising of 5 men and 5 women, however the | | | | obtained:t-Test: Two-Sample Assuming Unequal |
| sample in each category was obtained randomly, | | | | Varianceswomenmen |
| the reason for selecting a sample was due to the | | | | Mean |
| cost and resources associated with studying the | | | | 108.4 |
| entire population. | | | | 108.8 |
| Expected results: | | | | Variance |
| The expected results in this study are that mean | | | | 18.3 |
| and women are equally intelligent, and therefore | | | | 59.7 |
| the reason why women are do not hold top | | | | Observations |
| position in the society is because they are viewed | | | | 5 |
| as weak by men, the society do not give women | | | | 5 |
| a chance to prove their abilities, this can is evident | | | | Hypothesized Mean Difference |
| from history where women in the past did not | | | | 0df |
| hold top positions compared to today where | | | | 6t Stat |
| changes have occurred and women hold position | | | | -0.10127 |
| that were considered to be held by men only. | | | | P(T<=t) one-tail |

| In order to analyze the difference in intelligence | | | | P(T<=t) two-tail |
| between men and women descriptive statistics | | | | 0.922633t Critical two-tail |

| following table summarizes the results:womenmen | | | | while the T critical two tail value is 2.4469, the T |
| | | | critical value is than the statistics value and |
| 104 | | | | therefore the null hypothesis is accepted. |
| 109 | | | | Implications: |
| | | | The null hypothesis Ho: q1 =q2 is accepted and |
| 106 | | | | this implies that the mean IQ test score for male |
| 106 | | | | and female are equal; this means that men and |
| | | | women are equally intelligent. |
| 110 | | | | 3. Visuals |
| 119 | | | | A bar chart is more appropriate in this case given |
| | | | that there are only two categories and that the |
| 107 | | | | mean values are being considered, this graph aids |
| 112 | | | | in comparing data values and statistics such as |
| | | | the mean, the following bar chart indicates the |
| 115 | | | | mean value for each category: |
| 98average | | | | From the above chart the mean value for male is |
| 108.4 | | | | greater than the man value for female |
| 108.8standard deviation | | | | Conclusions: |
| 4.27785 | | | | Results in the above analysis show that women |
| 7.726578minimum | | | | IQ test score mean value is lower than men IQ |
| 104 | | | | test score mean value, it is also evident that a |
| 98maximum | | | | hypothesis test on the difference between mean |
| 115 | | | | show that the two mean values are equal, |
| 119median | | | | therefore this means that the population mean |
| 107 | | | | values are equal and that men and women are |
| 109 | | | | equally intelligent. Some problems with this study is |
| From the above table the average IQ test results | | | | that the sample size used is relatively small, |
| show that women have a lower average value | | | | however the T test method is the most |
| (108.4) than men (108.8), however the standard | | | | appropriate method in determining the mean |
| deviation between the two categories show that | | | | difference between men and female IQ score |
| men data have a higher standard deviation, the | | | | mean values given that there are only two |
| minimum value for women is 104 while the | | | | categories. |
