I dont understand the logic of the solution. The final return is a list of chi-squared_values, but in the for loop, we came up with only one number instead of a list.

Screen Link: https://app.dataquest.io/m/99/chi-squared-tests/4/generating-a-distribution

My understanding of the below code is to randomly take 32561 numbers between 0-1, if value >0.5 then we assign them as male, others are assigned to female. Then we count male and female. We came up 2 numbers, based on these 2 number we calculated `male_diff`

and `female_diff`

added these 2 numbers together, then we have one number `chi_squared`

.After appending it to the `chi_squared_values`

, why it becomes a list eventually…

My Code:

```
for i in range(1000):
sequence = random((32561,))
sequence[sequence < .5] = 0
sequence[sequence >= .5] = 1
male_count = len(sequence[sequence == 0])
female_count = len(sequence[sequence == 1])
male_diff = (male_count - 16280.5) ** 2 / 16280.5
female_diff = (female_count - 16280.5) ** 2 / 16280.5
chi_squared = male_diff + female_diff
chi_squared_values.append(chi_squared)
```
