Numeracy and Data Analysis of Berlin Humidity

The assignment involves analyzing 10 days' worth of humidity data from Berlin, presenting it in a tabular format with graphs, and applying linear regression models to predict future humidity levels for the 15th and 23rd days. The report also includes references to relevant studies on heat, humidity, and infant mortality in developing countries.

INTRODUCTION
Numeracy and data analysis are very important in this present generation as it shows
capability for understanding numerical analysis. The present report is giving brief analysis of
humidity of Berlin of past 10 days. The data will be analyzed in tabular format and reflected in
visual presentation as column and line chart. In the same series, this will provide description of
level of humidity with help of descriptive analysis such as mean, median, mode and standard
deviation in detail manner. It will represent about linear forecasting model was Y = mX + c with
calculation m, c along with forecast of day 15 and 23.
MAIN BODY
1) Arrange the data in a table format.
For present report the data is been collected is forecasted humidity of Berlin of next 10 days.
Days Humidity (in %)
14/05/19 41%
15/05/19 43%
16/05/19 52%
17/05/19 43%
18/05/19 54%
19/05/19 47%
20/05/19 48%
21/05/19 46%
22/05/19 55%
23/05/19 51%
2) Present the data using any two types of charts

3) Calculate the following and provide the steps for the calculation and highlight the final
Mean – It is the average of total values.
Step 1- In a blank cell just below last value write the formula for mean (Geruso and Spears
2018).
Step 2 – Select the cells for which mean value has to be calculated.

Step 3- Press the enter key to get result
Median
Step 1- Select a blank cell and write the formula for mediun.
Step 2 – Select the cells for which mean value has to be calculated.
Step 3- Press the enter key to get value
Mode – It shows the number that is appeared most number of times.
Step 1- Put the numbers in order by using sort function in excel and clicking on A to Z.
Step 2- Select a blank cell and write formula of MODE.
Step 3- Select the cells and press enter key to get result.
Range- It is the difference between highest and lowest values.
Step 1- Go to a blank cell and write the formula for range.
Step 2 – Select the cells for which mean value has to be calculated.
Step 3- Press the enter key to get result (Eymen and Köylü, 2018).
Standard deviation
Step 1- Go to a blank cell and write the formula for standard deviation
Step 2 – Select the cells for which mean value has to be calculated.
Step 3- Press the enter key to get result.
Outcome
Particulars Amount
Mean 48
Median 48
Mode 0.43
Minimum 41
Maximum 55
Range 14
Standard deviation 0.052
From above table it is analyzed that mean value of data is 48, the median is also same
that is 48. The mode is 0.43 which states that the most number that is repeated in data is 43.

Moreover, the minimum value is 41 and maximum is 55 so the range between them is 14. At last
standard deviation is 0.052 far from mean.
4. For the data, use the linear forecasting model which is y = mx + c to calculate followings:

CONCLUSION
It is concluded that the 10 days forecast humidify of Berlin is taken. The data is presented
in tabular format with graphs. Also, the linear regression model is used to calculate 15
and 23 day forecast humidity. The 15th day it will be 79% and on 23rd day it will be 90%.
