There is no data on those who identify as non-binary or transgender. The 2021 census questionnaire was updated to include a question on sex at birth and another question on gender now, which allows respondents to identify as a gender other than male or female. Discussion questions: 1) Change the graph category to Time and use the graph to estimate the 50" percentile, the 98th percentile and the 10" percentile for 2015. Does this give you a better idea about income distribution than simply knowing the mean median? 2) Change the graph categories to explore where differences exist between different groups (eg., age, gender, etc.) Note that this does not explain why the differences exist.Discussion questions 1) Why do you think the mean income is higher than the median income in all cases? Activity: Calculate the mean and median of the following incomes (given in thousands of dollars). 33, 45, 56, 62, 71, 150, 275 Which of these calculations better represents a "typical" income? 2) Activity: Calculate the mean and median of these incomes (given in thousands of dollars). 20, 20, 100, 100 Calculate the mean and median of this sample of incomes: 50, 55, 65, 70 3) What other information besides the mean and median might be helpful to help us to understand the income distribution in a country
