Medical data examination

Python

Hi everyone, I am having some trouble in passing one heatmap test for the medical data examination project.

Here is the link to my code:my project so far

and here are the errors I keep getting:

I can infer that some values are off and that I have more values than the ones expected by the test. But, I have scrolled through posts relating to this project and my code does not look that different from the code I have seen around in this forum.

I still have not picked upon my mistake though.
Many thanks in advance for your help!

The problem is here in your correlation:

def draw_heat_map():
    # Clean the data
    df_heat =  df[(df['ap_lo'] <= df['ap_hi']) & 
             (df['height'] >= (df['height'].quantile(0.025))) & 
             (df['height'] <= (df['height'].quantile(0.975))) & 
             (df['weight'] >= (df['weight'].quantile(0.025))) & 
             (df['weight'] <= (df['weight'].quantile(0.975)))]

    # Calculate the correlation matrix
    corr = df.corr()

hi jeremy thank you for replying and helping me out! Could you explain what you mean by that? I have seen many people working on this project add optional parameters to the .corr() method (such as the pearson correlation method) and I have read the pandas documentation on the corr() method but nothing I have tried seems to have helped.

I have also tried changing the mask, (bby adding things like np.ones_like(corr, dtype=bool)) but both things have not brought me any closer to passing the tests. What am I missing here?
many thanks :slight_smile:

You’re missing the variable name. df.corr() calculates correlations on df, not df_heat. You’re trying to draw the heatmap with df_heat.

Ah amy thanks! Sometimes it is the silliest error that trips someone up. Here i was checking and rechecking my maths, questioning on if I had cleaned the data correctly or formatted the data for the heatmap correctly :laughing: And in the end it turns out that my mistake was just passing the wrong variable to the function!
Many many thanks Jeremy, my code passes all the tests now!
