INTRODUCTION
Numeracy and data analysis refers to collecting, cleaning, transforming numerical data
with the object of getting useful information for decision-making. This report will show sleeping
hour of consecutive days and on the basis of this data mean, median, mode, range, standard
deviation will be calculated. In addition to graph, chart will be formed for future analysis.
Further, this report will forecast sleeping hours on the basis of forecasting model that is y = mx
+c.
