Analyse the full historical data, see what is the pattern of the numbers. Perform comprehensive analysis. Calculate basic statistics, identified the most and least frequently drawn numbers, and analyze the average gap between consecutive numbers. 

Solution

pandas as pd

Load the Excel file to see its contents

file_path = '/mnt/data/1735547819309xktalatk.xlsx' excel_data = pd.ExcelFile(file_path)

List all sheet names to get an overview of the file structure

sheet_names = excel_data.sheet_names sheet_names Load the data from the first sheet to inspect its structure data = pd.read_excel(file_path, sheet_name='Sheet1')

Display the first few rows of the data to understand its format

data.head()The dataset contains information on lottery draw results, where each row represents a drawing. The columns include:

  • DrawDate: The date of the lottery draw.
  • DrawnNo1 to DrawnNo6: The six numbers drawn on that date.

Next, I will perform a comprehensive analysis, calculating basic statistics, the most and least frequently drawn numbers, and the average gap between consecutive numbers. Let's start by analyzing the frequency of the numbers. Reshape the data to have all drawn numbers in one column for frequency analysis drawn_numbers = data[['DrawnNo1', 'DrawnNo2', 'DrawnNo3', 'DrawnNo4', 'DrawnNo5', 'DrawnNo6']].values.flatten()

Calculate the frequency of each number drawn

frequency = pd.Series(drawn_numbers).value_counts().sort_values(ascending=False)

Get the most and least frequently drawn numbers

most_frequent = frequency.head(1) least_frequent = frequency.tail(1)

Calculate the basic statistics of the drawn numbers (mean, median, mode, etc.)

basic_statistics = drawn_numbers.describe()

most_frequent, least_frequent, basic_statisticsIt appears that I tried to call a method intended for a pandas DataFrame or Series on a numpy array. I will convert the array into a pandas Series to calculate the basic statistics properly.

Let me correct this and proceed with the analysis. Convert the drawn numbers into a pandas Series for analysis drawn_numbers_series = pd.Series(drawn_numbers)

Calculate the basic statistics of the drawn numbers (mean, median, mode, etc.)

basic_statistics = drawn_numbers_series.describe()

most_frequent, least_frequent, basic_statisticsIt seems like I can’t do more advanced data analysis right now. Please try again later. Let me know if you need assistance with something else in the meantime!
