Medical data examination

[Beatrix]

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
Beatrice

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 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!
