 the scientific methods observations first the contents the scientific method making observations data data types first we'll discuss the scientific methods students scientific methods and common methods these two basic terms that we use in daily life scientific method is a series of steps followed by scientists to answer a specific natural problem scientific methods are based on facts and measurable evidences or scientific method they have certain steps the first step scientific methods can that is the observations observations simply observation come at a little bit here can you please go observe career in scientific terms observation means to observe certain issue collect the information regarding some specific scientific issue so observation can you have any big information collect that we use our senses we can use five senses of your mother total five senses of five is going to be senses you'll use the same sometime problem come observe by the visualizations sometime by hearing sometime by smelling the sometime by taste and sometime by touching the of the we get the observations from observation the information which we collect from observation that is called the data so it means data is the information which is obtained by the observations are from the observations so for getting observations normally we use our five senses but during scientific experiments scientific issues where our five senses are not so accurate we get the benefit we get the help of the scientific instruments the informations are data we obtain from the observation that may fall into main categories quantitative data and the qualitative data that information are that is in the form of number that is called the quantitative data just like we say number of persons count the height measure the weight measure the or then if you have fever then temperature measure these are all things which are data which is a numerical form I call quantitative data when there is some time some information which is a qualitative form observe the same sometime if we observe the shape color observe we can't measure the shape we can't measure the color in normal sense so colors shape such thing properties which are not in numerical form they are called the qualitative data so overall if you look at the quantitative data we need specific instruments like temperature measure we need thermometer if we have to wait for someone then we need weighing balance if we have to measure the volume then we require the different volumetric cylinder we will require but for qualitative data we don't need such instruments like if we have to observe the color we can simply observe the colors so if we have to smell normally we can smell the material we will smell it and take its observation so if you have to suppose if you have to observe its observation then you smell it and take its observation because you can't measure the smell you can't measure the smell because the smell or the color observation is the qualitative data
