I am trying to find a strategy to fill these null values. Is there a way to fill alphanumeric blank values? If there is no automatic way, I was thinking of fill these records based on Name, number of sibling, parent child and class columns. E.g. for a missing value, try to see ...
We can mark values as NaN easily with the Pandas DataFrame by using the replace() function on a subset of the columns we are interested in. After we have marked the missing values, we can use the isnull() function to mark all of the NaN values in the dataset as True and get a cou...
One solution is to fill in the null values with the median age. We could also impute with the mean age but the median is more robust to outliers. data['Age'] = data['Age'].fillna(data['Age'].median()) Let's now make some charts. Let's visualize survival based on the gender. ...

Using a Scatter plot, it is possible to review multivariate outliers, or the outliers that exist in two or more variables. For example, in our dataset we see a fare_amount of -52 with a passenger_count of 5. Both of those values are outliers in our data. On the x-axis use the pas...
CSV (Comma Separated Values) is a text file in which the values in columns are separated by a comma. For importing data in the R programming environment, we have to set our working directory with the setwd() function. For example: setwd("C:/Users/intellipaat/Desktop/BLOG/files") To rea...

pandas.reset_index in Python is used to reset the current index of a dataframe to default indexing (0 to number of rows minus 1) or to reset multi level index. By doing so the original index gets converted to a column.
