If you can get the correct value then amend the record. But it may be too late for that - you may not be able "to go back in time" to obtain the correct value. In that case, make a note of the faulty data point and either exclude it from analyses. If the data are multivariate you may be able to estimate the "true" value but will have to give up a degree of freedom in any statistical analyses.

Observation and record keeping are important as you will need to redo an experiment many times to prove that it actually works.
it should say if it is ppm or ppb what ever unit they were working in. 25 is too vague
He should relax, try not to hover over the apparatus or worry about the results, and try to manage his stress and conserve his energy, perhaps by having a warm drink or some light refreshments, reading the newspaper, going to a movie, singing a song, or taking a nap. That way, when the experiment has finished conducting, he will still be fresh and alert enough to record the data accurately, and interpret it correctly.
So there exists a record of your experiment that others, or yourself later on, can refer to.

Scientific experiments are supposed to be repeatable. When you are conducting an experiment, you need to fully record your procedure including any equipment, and use diagrams as well so that any scientist can follow your procedure and get the same results that you did.

To measure meter accurately in a scientific experiment, use a ruler or measuring tape with clear markings in millimeters. Ensure the object being measured is straight and aligned with the measuring tool. Take the measurement at eye level to avoid parallax error. Record the measurement to the nearest millimeter for precision.

To create a data table for a science experiment, you can follow these steps: Identify the variables you will be measuring in your experiment. Create columns in the table for each variable, labeling them clearly. Create rows to record each data point or observation. Include units of measurement for each variable. Ensure the table is organized and easy to read, with a clear title at the top. By following these steps, you can effectively organize and record data from your science experiment in a data table.
The key steps in conducting a sugar and water experiment are: Measure and mix the sugar and water in specific proportions. Heat the mixture until the sugar dissolves completely. Allow the solution to cool down to room temperature. Observe and record any changes in the solution, such as clarity or color. Compare the results with the initial measurements to analyze the effects of sugar on water.
