Hi! I am getting confused about the chi-squared test. I believe I did something wrong on my code and that is why my final answers ( chi_squared and p-value) are opposite to the solution answer. 10 Chi-squared I got are really close to each other, P-value I got is all 0.

I am not sure that I understand the logic of the code and the process of getting the chi-squared value. In the previous course, we learned that the chi-squared test for categorical data. This test enables us to determine the statistical significance of observing a set of categorical values. In this project, we try to determine if there is a significant relationship between terms_used and question value, but how does it help to answer ââ How often new questions are repeats of older questions?ââ

Thank you.

My Code:

```
from scipy.stats import chisquare
high_value_count=df[df['high_value']==1].size
low_value_count=df[df['high_value']==0].size
chi_squared=[]
for list in observed_expected:
total=high_value_count+low_value_count
total_prop=total/df.size
high_value_exp = total_prop * high_value_count
low_value_exp = total_prop * low_value_count
observed = np.array([list[0], list[1]])
expected = np.array([high_value_exp, low_value_exp])
chi_squared.append(chisquare(observed, expected))
chi_squared
```

What I expected to happen:

chi-squared values are different and p-value are different, like solution answers.
